Sasuke would not have lost the Rinnegan anyways, it was awakened "naturally" in his body like the Mangekyo was pretty much. He still had hashi dna therefor ashura chakra too so he would never lose the Rinnegan once he awakened it. Naruto was never again seen using that form or anything and Retsu no Show pretty much solidifies that he lost it.
