Sasuke does not possess Six Paths Senjutsu. He never did.

situation: Hagoromo and hamura already had TSB before sealing juubi/kaguya

question: this confirm the brothers already had six path senjutsu? As far as i'm aware, Six Paths Senjutsu is a requirement for TSB's. Becoming the Juubi Jinchuriki is one way of obtaining SPS, but e.g. Toneri and Hamura possessed TSB's as well, and so did Hagoromo before becoming Juubi Jinchuriki.

Also, Obito did need the biju, but only a portion of a Biju works. Same is true for Naruto after all. This does result in a significantly weaker form, which is why Obito's juubi needed some time to reform itself (It was also missing an arm) whereas Madara's was full power from the start.
