Answer: It emphasizes the tedious details of Usher’s beliefs.
The way the author employs parallelism in this passage emphasizes the tediousness of Usher's beliefs and personality. Usher is an intellectual character. He is not particularly lively or interesting. Moreover, the story shows that Usher's mind is relatively weak, and the story traces his journey to insanity. These mental deficiencies are emphasized in the passage.
