in GAIDEN, sasuke stated to naruto that his rinnegan "power(s) has faded" which is why his rinnegan looked like nagato's. but when it was fully charged, it took the form of the tamoe form. that alone, should confirmed that sasuke's rinnegan and nagato's rinnegan are not the same and shouldn't be compared.

His Rinnegan having a cooldown period is the same thing that happened with Danzo using Kotoamatsukami with Shisui's MS. That does not make it a new dojutsu. The full power line was a description, and explanation, not an actual title.
