Like I pointed out before it was a dropped plot point. The context is in the Kage Summit when Danzo is found out and Ao notices the eye and its chakra( he says it is Shisui's which is correct and he also says the arm has Shisui's chakra which is also dropped and retconned later on too), and compares it to Yagura's case. Originally it was gearing towards it being Danzo who controlled Yagura like that but it was dropped and randomly given as an event to Obito which he never again used afterwards(clearly they didn't know what to do with it). Otherwise Killer B and Naruto would have been defeated with zero issue as Obito would have done the same to them as he did to Yagura who was a perfect Jinchuriki.
