You are correct that getting a cross-up if there is space between the edge and the collision box is not a glitch.
What is a glitch is why that space is there. He did an air throw into the corner. There should be not space between the edge and the collision box.
But H-VSion's air throw puts the opponent in a back turn state.
I'm 99% sure that back turn cross-ups in the corner are a glitch that got fixed, and will no longer work when we get CC1.07.
If they really intended for this type of back turn cross-up to be possible, why did they not include corner cross-ups for just jumping over the opponent? (AH3 Style)
Why no cross-up after a 2C in the corner? Or a 5A6AA6C?Or any other down except a back turn, and close to wake-up, corner cross-up? Why no space for cross-up after these?
I definitely agree that you should get a cross-up if you create that space with a 623C set-up or something similar, but just back turn in the corner?
Seems like an obvious glitch to me. Like they just missed telling the game that back turn situations can happen other places than mid screen. Like they said:
If mid screen, then back turn = cross-up. And back turn = cross-up is still true even if mid screen is false.
