Based on that, we can look at the mangekyous of Kakashi and Tobi, both "warping abilities." Kakashi has the left eye, an offensive warping ability, and Tobi has the right eye, a defensive warping ability.
Plus, there is the fact that Kishi has made it painfully obvious ever since showing Tobi with a sharingan, and only people in denial refused to acknowledge it.
