Yun dive kick fake cross up

[media=youtube]oQoWrKHSn9g[/media] , at 2:55 yun does the dive kick but doesnt cross up even though i believe it was a Fierce dive, can someone elaborate on how it works and if its character specific or not please

Yun can’t crossup yun in the corner unless the yun on the ground’s head is facing away from the corner ie: from a throw. Since he was knocked down with an attack his head was facing towards the corner which means the positioning of the sprite does not allow it to cross up.
