In Dissidia, if you used a Dodge action you could cancel out of the cooldown of an attack, and sometimes be able to lead into another attack while the opponent was still in hitstun.
Return Cancels were similar, but when you dodged, you would move the analog stick back and forth really quickly during the move, so you'd like...dodge back and forth in one motion. Return Cancels also cut down on the animation frames of the dodge, so you could act sooner than a normal Dodge Cancel.
If I remember correctly, it was discovered when someone tried to do a Turn Cancel, which was when you would dodge to a side of the enemy by sweeping the analog stick (sorta like a down-to-forward fighting game input) to dodge and stay near the enemy at the same time.
These didn't work on the ground, though.
So I'm just curious to see if their mechanic might have a similar feel to it, and if it's possible. I know it's a long shot, but eh...might as well try
