I need to understand how "prey drive" fits in
Prey drive is not mentioned on that page.

since the excercise affects the magnitude or its intensity.

I don't think it affects the magnitude or intensity of the prey drive. It may refocus it toward you, but it doesn't wake it up or anything. The prey drive is there and may be manifesting as stress (or aggression) but it doesn't create or intensify the prey drive where there is none.
It actually does increase the intensity of the prey drive in a way because it teaches the dog to work past his internal resistance; the less resistance he has the more his drive is expressed through behavior. It's a bit like reducing the drag co-effecient in an airplane or race car.
When wolves hunt large prey they have to overcome a lot of resistance -- internal and external -- in order to be successful. External resistance can come in the form of rough terrain, for example, or a herd of bison who refuse to run, or a deer who turns and "brandishes" his antlers at the pack. Internal resistance is a bit harder to see but since the pack has to expend a lot of energy when they hunt, they have to work past their fear, their levels of tiredness, etc. It also seems to me that nature has created a system where the wolf doesn't
really want to hunt large prey if he doesn't have to. That in itself is
a form of resistance built into the equation. That's why endorphins are released at each stage of the hunt.
So what motivates the pack to finally get off their collective asses (so to speak) and go look for something with hooves to feast on? They have to be pretty hungry. And since all behavior is based on levels of tension and release, tension builds with the hunger, and is released through the hunt. So in effect, part of the prey drive is this build up of tension. In other words, even though hunger is part of the equation, the prey drive itself operates by building tension in the animal. Hunger only brings that tension into sharp relief, if you will. And I say this because the primary release point for tension seems to always be through the teeth and jaws. This is why most dog owners have baskets full of rawhides, bones, chew toys, etc. Nature has designed canines to release and reduce tension through biting.
As a sort of side note, this business of the prey drive building tension inside wolves is one reason we've been getting false information about the social dynamics of wolf packs. Most of that information came through observations of captive wolves, culled from various sources, who didn't really know one another, and more importantly, weren't given a chance to hunt and kill large prey on a regular basis. So even though they were fed regularly, their prey drive was still active and building tension inside them. And that tension needed an outlet, so the wolves offloaded their predatory emotions and tension into conflicts with one another, the types of conflicts rarely seen in wild wolves. Why don't wild wolves act the same way captive wolves do? The primary reason (among other things) is that they already have a natural release point for tension--collectively hunting large prey.
It's interesting to note that at Wolf Park (where the wolves are given a chance to chase and I suppose "harass" buffalo, but are never allowed to actually use their teeth and jaws to kill them), the wolves don't exhibit the same kind or level of hierarchical behaviors we see in other captive wolves. They do exhibit some of those behaviors, though, because they never get a chance to actually kill the buffalo, just to do everything but, which is probably why the people at Wolf Park still seem convinced that the wolves there form hierarchies. But I think that's only because they're not getting that final payoff through biting that nature has designed them for.
So what does this have to do with the pushing exercise? It teaches the dog to work past his internal resistance, that's all. It reduces his inhibitions. So while Kim is sort of mistaken when she says the exercise is just operant conditioning, in a way she's not. The reason is that the behavioral scientist tends to see things more through the lens of behaviors than through changes in internal states. And what's being "conditioned" or positively reinforced here isn't one specific behavior, but the wellspring of a whole host of related behaviors and feeling states.

So in other words I don't always think of "prey drive" as always being associated with food or the only means to satisfy hunger.
I don't either... But that isn't being questioned. Or implied or anything.
(Is it?) Are you possibly making a connection where there isn't one? I'm sure LCK can answer your questions better than I since I am brand new at this particular exercise. LCK? Hello?
