I believe the reason why Sasuke using one rinnegan at the moment is to get accustom to it powers .If Sasuke was using both his rinnegan then he will be using up alot of chakra and not knowing his their abilities.So Sasuke is just mastering one Rinnegan/sharinnegan jutsu then he work on the other one.
I know some of you Sasuke hater will deny my comment ,but Sasuke went through the same experience as Madara.Madara unlock a pair of rinnegan,not just one rinnegan,therefore Sasuke have to both.Obito said this twice,when two sharingan eyes unite,then their ultimate power will be unleash,so far we have not seen Sasuke at his best.Sasuke is just in the testing phase,probably when Madara become worthy enough (having both rinnegan) then Sasuke will use his best.Sasuke right eye should be able to change to EMS too,it should not be base sharinegan only,he need to use susano for defense against any madara jutsu.This also prove that Sasuke will unlock his rinnengan/sharinnegan eventually.
