Airborne Lenny from Big Band & Fall Speed

[Broseidon Rex]

I've found that two attacks that use Sound Stun (cHP and H Cymbals) will actually lift Lenny off the ground, most noticeably for Cymbals. Additionally, the timing of cymbals near Lenny detonation makes him fall at different speeds. If it's a couple of frames before, he stays in the pre-explosion frame until he hits the ground and explodes normal. But if you hit him closer to detonation, he gets dragged towards you and fast falls, followed by explosion. You can ignore the second part of the video with the Giant Step, @Stuff explained that no earthquake is generated if only Lenny is hit, similar to Ms Fortune's head.

My questions is whether all of this was intentional or should Lenny be grounded at all times.

This all came up in a match vs @AtroxChobatsu
