There is a reason why sasuke has rinnegan only in one eye, it is somehow related to the infinite tsukoyomi!
So6p gave sasuke rinnegan just because it will help naruto and sasuke to deactivate tsukoyomi, and once madara is defeated, it will disappear and sasuke will have only eternal mangekyu sharingan!!
That's the only reason why sasuke's rinnegan doesn't have other powers of rinnegan !!
