He feels like he is looking into a mirror; one that shows a superior version of himself. The version he aspires to be. A skilled expert, capable of conveying the most intimate feelings with the simplest, shortest sentences. The style could so easily lead to rambling but the author's control is perfect. The undercurrent from unspoken desires is readily apparent.
He is encouraged that his goal is not unattainable, and is something that would make him proud. So maybe it is not quite a reflection he sees. His future self, he hopes.
