Yun/Yangs jumping arc

third Strike newb here. I am trying to unlock everything in the game, so I have to play and fight against everyone. One thing that I noticed is that Yun/Yang seem to be able to control their jumps quite a bit. I have seen the computer do what looks like a straight up jump, then arc the jump forward or backwards, moving them just a little bit forward or backward. I have tried, but I cant seem to get it. Is this a CPU thing only, or am I seeing things?

whenever yun or yang super jumps straight up and down, they move backwards after the apex of their jump.
