@pathfinder Does Stay down proccing on an enemy standing up prevent Reactive Strike of another character from working on that same enemy? Does Topple Foe from Marshal archetype attempt to Trip an enemy before or after the Reactive strike if the trigger was a reactive strike for re-prone pseudo-Stay Down purposes?

Reading through some other examples, it’s definitely a mixed bag of wording, with some saying “attempts” or “begins” or otherwise implying before the action is complete, and some saying after.
I’ll stand by my original claim that the correction should be “attempts to Stand” though, because reactions occur after the trigger is complete, you can’t disrupt an action after it’s happened.
