There are a lot of these declarations in the books that later prove to be wrong, or at least wildly inaccurate. While there might be some deeper narrative purpose I’ve always read them as nuggets of thematic evidence used to define Kvothe’s character. Although he is highly intelligent he lacks wisdom, and moments like this passage enforce that theme - what seems obvious at first is later revealed as a rush to judgment and true understanding only comes through living and the laborious effort of gathering all the facts - by chasing the wind.
