B-reversed air dodge?

[Zerynx]

For a while, I've had this bothering me. I see people being able to maneuver their air dodging character as if they had just performed a B reverse. I've seen it performed in many tournaments, but no one seemed to be surprised by it or mentioned it at all.
Here is where an example from an AceStarthe3rd video, where I first saw it:

I tried to recreate it, it's just that toon link has a very high air maneuverability. Jiggly can do it even better.
