^Again, not farfetched theory, plausible theory.

Anyway, while I admit it is possibility that it's PS around Kurama in case of Madara(despite not having clear evidence that he could use it alive before VotE in the manga), in Sasuke's case it's pretty questionable.

Also... That would be just TOO simple explanation.
