As I understand it, the author was sharing the story to convince the audience he was a good writer and, thus, we should value his opinions on how to write non-fiction.
This was the intention. Originally it was more clear but I moved the other half of the story to the conclusion where it's even more evident that the stories were a way to build rapport and establish some kind of credibility.
I like these abrupt switches that tie-in later. Kind of like a b-roll but in text.
