Think you're using "staleness" wrong here but yeah you're right. But that example supports my argument. The guy running into the fsmash is getting hit on the opposite side of usual, so the fsmash hit is reversed.
Going back to the thing you said about hurtboxes and hitboxes, I think that's where my confusion came in, maybe? When I hear hurtbox I think of the vulnerable parts of a character, one that is being attacked, and when I hear hitbox I think of the attacker's move, be it an aerial or a smash or tilt or whatever.
I thought you were saying it's wholly dependent on where it is the person is
being hit.
Unless you still are and we're on two different pages.
[/quote]Then what does it depend on? Like you said in your fsmash example, you can get a reverse hit ANY time during the move. Same thing can happen with Samus bair if you bair and somebody goes into your back during the final frames. You get a reverse weak bair.

It would depend on what part of your bair connects with the opponent, wouldn't it? And have nothing to do with what part of the opponent it connects with?
In Samus's case, knockback is horizontal if the opponent is hit by her foot, calf, and part of her thigh. Knockback is reversed if the opponent is hit by the upper part of her thigh or her hip.
Or maybe this photo of falcon's fsmash, facing right, will illustrate it:
my plan of getting drunk and trying this did not work out. i'll give it a go when i get back from class.
