I mean, it's weird. We don't know what to call this thing. Maybe they just overlapped each other? If so, where would Sasuke's Sharingan go? I believe it should be considered something like Madara's evolution into the Rinnegan, where it still possesses the power of his Sharingan. Maybe that's why the SoSP stated that his mother possessed the power of the Sharingan, not the actual eye. And this is a loooot of theories.

But lets just call it a Rinnegan, because we have no real information on what it really is.
