Oh, misread. 

Anyway I was assuming that Itsuki would hot the ground long before the sword comes back around, cause the way I see it, once judgement did the first swing all she did was hop up very slightly and tuck her legs into her chest, curling into a sorta ball. Not extremely high up into the air but just enough to hop over the sword and then almost immediately land by re extending her legs so they hit the ground pretty much immediately. 

Which is why, in my post before this, I already had her back on solid ground and dashing past Judgement before you no sold that.
