I'm pretty sure he has to be in the district to jump in on the fight. I've seen him jump around districts a few times, he was in downtown decatur and then a few minutes later he was gone.

It probably has something to do with the way the user list is sorted. If you sort by locale, he doesn't show up with the other npc's, but if you sort by id, he'll show up right after the other npc's. The database probably doesn't use a secondary sort, so it just sorts the characters in the order they were added, or it's using a hidden field.
