No, its doing a small, very small mind you, one jump, and then double tapping down fast, so you fall from this small jump fast, and just before you hit the ground you block doing an air dodge in the direction you want to go. It can be linked together, so you look like you are sliding across the stage on waves of the air from when you hit the ground in your dodge, and it makes it so you can't be hit when you are walking, not as much anyway. It's kinda hard, I'm not good at it, I just block if I am going to be attacked, or I counter.
