Yes, as it says there, in the case of event triggers, both TriggerUnregisterForPlayersm and ProcTriggerUnregisterForPlayers, as well as any other calls that register or unregister triggers, won't do anything, because an event trigger is meant to be a trigger that's registered for all characters at all times.
However, it is best practice, both for ease of debugging and for performance reasons, to use registered triggers rather than event triggers unless you actually need a trigger that throws events for every possible character (as is the case with e.g. weather - absolutely everyone who walks into rain, gets wet) or depend on the OnTriggerEnter event in behaviour script.
