From the monster point of view he is already finished - everything else is dead after dropping down. Monster would have to know he is fighting with somebody with PC template to understand that he should be coup-de-grace'd to get really dead.
I doubt monsters will have a lot of experience with PCs. Generally, information flow goes other direction. Some powerful NPCs on the other hand... they could have noticed that for very few people in the world laws of the reality work in different way. I have a image in my head where PC is put into some kind of hellish device and high-level NPC wizard is trying to extract those 'healing surges' from him. After all, ability to heal all damage overnight is a nice kind of superpower.
