@Squinty97:

Obito can choose what he sends to next dimension, when phasing, so even if he was burning, Amaterasu wouldn't go with it, if he doesn't choose for it to.

Obito may be touching Amaterasu, but the portal is on the front of his head, not the back. The black fire on the back of his head would be unaffected. Obito would be caught unaware thinking he got Itachi, so it's unlikely he would be in sensor mode, if he is a sensor. Besides Itachi can just opt for Gokakyuu or shurikens instead. It would have the same effect. Kunais can actually kill him from his blindspot actually.
