Sasuke is fulfilling his role as the "hawk", who focuses on keen insight. If you look at the previous chapter and now the latest one, it becomes obvious that Sasuke is in deep thoughts about the Shinobi world. If people are reading Naruto for the intense fighting scenes than this will mean jack to them. However, I'm pretty sure Kishimoto intended to place a lot of symbolism in his manga, and there are several examples as proof.
He's trying to do the opposite of "going with the flow" of things. While other people may take things as "a village", "a shinobi", or even "a clan" as a vocabulary word, Sasuke wants to know the fundamentals and the components of these things. This is at least what I think Sasuke is being developed into.
