It would seem that once a 6 Paths, always a 6 Paths, since Naruto and Sasuke still have it. I don't recall Obito taking any 6 Paths chakra, just some 1&8 tails chakra. He was also basically dead until Naruto revived him, so any 6 Paths chakra he had left that wasn't his should have been gone or insignificant.
