I understood it a little bit as I have previously done some study of the brain as well as reading Thomas Hanna's books on somatics.

What I don't see in the text you pasted are what specific exercises one would do for TOS, or how one would derive what exercises to do for a given condition.

Tying into Holles comment, it looks they have rediscovered Feldenkrais type therapy.

Personally, I just need my damn neck muscles, intercostals and pec minor to stop ratcheting my ribs up.
