May well be.

Ironically, the most common place I read the tic of ending a piece of persuasive with a deliberate, unconnected conclusion that doesn't persuade and instead equivocates or states a trivialism ... is in student papers or similarly graded-like-assignments rote work.

Could be that there's a lot of that out there such that it's heavily represented in training data. Could just be a person doing a not-great writing job.
