Since that quote chain was getting so long, I decided to not quote. xD
Replying though, Sasuke advancing a tomoe is totally different from learning 3-tomoe specific techniques upon unlocking it. It was not until Part II that he was able to suppress the 9-tails influence using his sharingan. Due to Taijutsu training, he already had the speed and reflexes to counter Naruto, he just needed the insight to do so.
Which is what the 3rd tomoe granted him.
Indra's reincarnation might have granted him the spirit to get dat eternal mangekyou and all, but it's a stretch to say that it allowed him to master/become very adept at the Six Paths techniques just by mere observation of some of its usage.
