Relax! This is perfectly normal. There may be a female in the area who is in heat or maybe he just had a dream.
There are glands on the canine penis that swell when the male penetrates the female - and at other times as you saw. Those glands are the reason that one should never attempt to pull apart a tied male and female. The female can be very badly hurt if the glands have not gone down.
Many neutered dogs still have enough testosterone that they have the desire and the ability to tie with a female in heat. The guys are shooting blanks, but they don't know or care. <grin>
