or he got up because he wasn't experiencing crippling vertigo anymore that previously left him unable to do anything but hold the area where the damage was initially done.
that has never been stated.
yes because
Boruto hits you with it like a normal Rasengan and you take physical damage, and then the effect kicks in and you get hit with vertigo.
notice how Code only ever says,
why is everything spinning? and not why I am still being damaged?
Boruto never said that.
also hypothetically, if Hidari got obliterated by the initial hit and was "tanking" some form of residual AP from Uzuhiko, then logically the AP Uzuhiko would be doing overtime would be unquantifiably inferior to the regular damage done by Uzuhiko.
So it would be something that is unscalable to the Uzuhiko value at all.
nothing has proved that except via misinterpreting a statement and assuming Code holding his stomach means that he's being continuously damaged and not just that he's in pain.
