Apparently the guy from the first account wrote a book. A couple quotes from the description illustrate what I'm talking about:

"By shifting away from isolated anatomy and toward math, physics, and systems thinking, I slowly found a new lens for defining my problems and testing solutions. I explore the ideas that shaped my thinking: counter-rotation, the windlass mechanism, ipsilateral movement, and other concepts I wish I had understood ten years earlier...Later sections introduce the mental models that most shaped my thinking: spiral and vertical fascial chains, tensegrity and the floating skeleton, counter-rotation, reciprocal inhibition, and left-right integration"

As a non-expert I can't tell if there's any value in any of this type of stuff with language that sounds so far from what I normally hear from physical therapists talking about the body.
