Point is.... Originally, Sasuke was much much faster than Naruto. Naruto with Sage Mode or/and chakra mode is equal in speed to Sasuke. Only Naruto in those modes using Body Flicker is faster than Sasuke.

So Sasuke matching Naruto's speed is not an error or plothole or anything, it's a fact, since Naruto started out as the slower one and only thanks to those modes caught up to Sasuke's speed.
