I think you're reading the last sentence too literally which is probably not the way it was meant to be read. Instead it is simply a compliment to the author.

And if you really want to be pedantic then please also note that the sentence does not say "more accurate", it says "better". This can mean many things: more entertaining, more inspiring, and yes, also more accurate. But because "better" is rather vague, I don't think it's very fair to criticize it as irrational.
