No, all Sasuke did was put all the chakras into the Susanoo as a vessel, just like with the Demonic Statue, he didn't reverse COAT's effect and make it back into the pure Ten-Tails chakra as if it was never separated with COAT. He simply used his Susanoo as a vessel at the same magnitude that Obito and Akatsuki did with the Bijuu's chakra to the Demonic Statue.
