well when he was talking to sakura in the kamui dimension he stated that he could only transplant one of madara's Rinnegan because it was far to difficult to use both and that it was still to powerful of an eye it would stand to reason that it would be difficult to do so when being the shinju Jinchuuriki. also maybe he felt he did not need it because he was effectively immortal
