I still can't undertang what's the problem in this argument. We should just rely on the statements which were explicitly stated in the manga/databooks/other official sourses. So:
 * Black Zetsu saw Sasuke's Susanoo blocking the light of IT and stated that the Rinnegan allows him to repell the genjutsu. No more, no less. It means that Rinnegan itself is immune to IT, Susanoo just can exteng the range of immunity to cover the other people. What Sasuke did was only enhance the Susanoo with his Rinnegan ability, a principle similar to Sasuke using Chidori through Susanoo which doesn't cancel out Sasuke's capability to easity use Chidori without it, but the sutiation called on to do so.
 * Secondly, Sasuke warned Naruto not to go outside since he'd be already affected by IT outside of his Susanoo. Sasuke knew Naruto possessed the SPC and Naruto's several new abilities (Tailed Beasts' powers, TSBs), yet he still said Naruto would be got in IT anyway. It means that only visual prowess of the same calibre (i.e. the Rinnegan) can counter IT, and any other Six Paths powers wouldn't be enough.
