@BrainBrand the fact that we don't see the Amaterasu on the floor means it's more likely gone.

Besides, at that point Obito himself being burned by Amaterasu. It wasn't like it hadn't touched him yet. So by that point his own body is burning, so if he sent part of his body to Kamui then it would just be burning in Kamui's dimension and not solve anything. Makes more sense to remove it from himself somehow.

Also, Obito could abosrb it from the back of his head because he's touching it and it's been established that's what he needs to absorb things. But how is Itachi hitting the back of his head anyways? Itachi requires intense build-up for Amaterasu (and MS techs in general) that even non sensors and non sages have noticed coming. He can't exactly just fire it off like Sasuke
