His rinnegan is different to that of the Madara's or hagorama's.
IMO, it's because Indra had the chakra + eyes + spiritual energy of the sage. The sage gave sasuke directly those powers from himself and since he was the juubi Jin, so maybe he got some of the juubi chakra along with his the sages which enabled him to awaken a rinnegan that is unique to only him and the juubi?
I don't know. Has this been explained in the manga or am I missing something?
