You are misunderstanding it. Flawless pool is those people who have gone flawless this weekend & visited the lighthouse. Non-flawless pool is everyone else. The glows last a week (or more) so that has no indication of this week’s standings.

I've gotten on multiple occasions notifications at the end of matches that players are granted mercy and fall before the lighthouse, and just now get broken passages. It's not just glows

And? That just means that passage they were on has either used their mercy or the got a loss on the card. Has absolutely nothing to do with whether they are in flawless pool or not.
