Hey, author here. The writing on this section was a bit tricky to get right, but we did our best to keep it as clean as possible while still being precise about the concepts we were considering. And it's definitely not perfect; I've just made some small edits to hopefully make things a bit more clear.

This blog post is a response to ongoing discussion with the Bayesian community, so it was primarily aimed at a more technical audience. If you have any suggestions for how to make the writing more accessible, without becoming so overly expository that the mathematically-robust folk lose interest, I would love to discuss them.
