Planing bowed boards

TJD Edmonton
I was planing a bunch of oak boards for a friend and we found some of the boards had bowed, no surprise.
My friend, a structural engineer, suggested we plane the concave side to the cutters as this might relieve the stress that caused the bowing. I was was a little skeptical but OK we'll try it. Most of the boards showed a marked improvement and some, a small improvement with a couple that didn't change much. The boards have now sat for a week and the big improvement ones have relaxed completely and the others not so much. The ones that didn't improve got worse.

All in all a surprising experiment. Has anyone else tried or seen this?
