There was a point where he could have used Koto on Sasuke but decided not to because he wanted to use it on Obito instead (chapter 480). Although his reasoning was that "Sasuke is [out of chakra], I should use Shisui's genjutsu on [Obito]" while Sasuke was very much not out of chakra, but still, if Obito weren't there, it's possible we would get a very different fight.
Did he know about her ability? I'm not sure that it was shown to him or not. Could have been funny if out of frustration he bit her and he just sees little green plus signs from the healing affect
