Theres a video somewhere on youtube where he talks about this. I binged a lot of his videos lately so im not exactly sure which one it is, but its definitely on there somewhere and expands on what you quoted above.
On a side-note, I recently picked up the 1956 club edition pressing of A Love Supreme. This was pressed at Capitol's plant in Scranton PA (no VG stamp). My other copy is a VG stamped 1968 mono pressing and I always thought this to be a fantastic pressing, so much so that I never actively looked for an upgrade. When I saw the Club Edition for sale I did a bit of research and while there are mixed reviews, the majority were great and Steve Hoffman even claimed it to be the best pressing at one point. Have to admit that I'm blown away by the pressing quality, it's stunningly good. Quite surprising considering Van Gelder wasn't involved, but fantastic all the same.
