Well, for the most part the face licking is a puppy behavior designed to prevent the bite response from an older strange dog, that is if we are to believe that dogs are inherently wolves. The licking also stimulates the adults to regurgitate food for the pup. So what your Iggy is saying to those people is "please don't bite me, I'm a puppy, feed me instead."
Your pup already knows and trusts that you won't be biting him so he doesn't have that same need or drive.
Also taste and scent are tied to each other. Scent being the sense that stimulates memory moreso than any other. So it could be that your pup is trying to "remember" the people he meets.
I know that's probably a bit more dry of an explanation than you probably wanted, but it's a logical one.
