And the answer is simple, manga said rinnegan gives the ability to use six paths, just because Sasuke only showed 3 means he only has those and only those?:sdo:
By your logic Madara only has 3 too despite being the original because he also only showcased the same 3 Sasuke used. :elmo:
I guess Obito's sharingan doesn't have precognition because he didn't show it, Itachi and Madara can't copy ninjutsu, because for some reason , also Naruto's tsb can only change into rods because he was only shown that despite other TSB users changing it to other forms. :lol
This piss-poor logic applies everything. :vision:
