Pro-tip for the impaired of thinking;

Sasuke didn't call it a Rinnegan technique.

He merely said that a genjutsu which was cast by a Rinnegan can only be defeated by another Rinnegan. Anyone with two lobes in their brain and even an elementary understanding of Naruto realizes that the ability to cast genjutsu comes from the Sharingan, which the Rinnegan is an evolution of.
