When Defeating Bosses

This may happen in the first game as well, so feel free to move this thread if that's the case.

Why is it that if your party members are knocked out when you defeat a boss one of them, whether the other one's knocked out or not, automatically revives with a tiny bit of HP, even though the actual amount of time they are knocked out for hasn't passed?

Example at 5:21 here:

 

I looked up some Boss fights on Proud mode, and when Goofy went down Donald's HP didn't rise at the end like in that video. Maybe it's just a difficulty level thing?

Edit: Oh, this was on Proud Mode also. Huh. That's a bit strange~ I did see another video of the same fight, but this never happened. So honestly I'm not sure~ I do see what you mean though.

 

It's random, actually. It's either Donald or Goofy, not both, if both get knocked out just right before the boss is defeated.

As for the difficulty, I don't think it's really anything to do with that. as it's done that on Beginner Mode and Standard Mode as well.

I also noticed their HP will sometimes increase even when not knocked out. Watch from 8:50 to 9:50 here and pay attention to Jack Skellington's icon:

Although I think what @iwantedtoexplode just said makes complete sense.

 

in Kingdom Hearts II, at the end each fight you get a bonus for fighting. in the first fight you see that goofy learns the goofy tornado. you also get health and magic bonuses as well. the thing you pointed out was the bonuses in health. When your partners health increases like that, his/her health increases by the same interval. so if health is 0, it increases by the bonus. KH I doesn't have the bonuses. (unless it does in the 1.5 remake, I haven't played that one)

 

Actually, it does. Look at 31:39 here:

And with that, I'm going to have this moved because I was wrong.
