Madara says Obito had already had that power before, he was referring to the Ten Tails Senjutsu which is no different than the Six Paths Senjutsu according to Madara saying he had that same power when commenting on Naruto using SPSM. So no Obito did not take the normal Senjutsu, he took some Six Paths Senjutsu from Madara and that same Senjutsu was given to Kakashi to use later when Obito lent Kakashi his chakra.
