Somebody explain this weirdness to me, PLEASE

You do 2 beams while falling in unfly state. Not post normal jump.

2 AHVB? Or 2 reg. Air Viper Beams?

Im confused bc I thought he could do 2 sj. AVBs no matter what. The unfly randomness I’ve seen is TK AHVB or TK VB, then mash on the way down to get a normal to pop out. Please set me straight bc I’m not sure that even is related to Unfly.
