Please, clear your mind of metaphors for a moment.
In this game, moving into a conflict is synonymous with participating in a conflict. It is not an issue of timing. It is an issue of how game mechanics are defined by rules.
This is a reaction to
- any character
- moving to
- a conflict where Ide Trader is participating
When "character" = "Ide Trader," "conflict to which Ide Trader moves" = "a conflict where Ide Trader is participating."
