No, he said they took their schedules and ran some scenarios. He never claimed to talk to a single reserve.

I'm Y2K LUAL hire so that means most of my career has been on reserve. I've learned how to play a LOT of reserve games, and I've watched crew schedulers counter reserve pilots' games.
If anyone thinks that a reserve being on the hook for more hours at the front of every work block will 'fix' schedulers' reserve games, then they haven't been on reserve for a very long time, if ever.
There are sooo many different levers that schedulers can pull to get their desired outcome. This TA may close a couple of those levers, but not enough to make a difference.
