You don't even know what he's been giving it out for yet and if in fact he has been doing it as all you're going on is the post of one person, but how would this be any different than people getting merit for their posts/threads in Meta or Reputation for helping out and reporting/busting spambots, farmers and merit traders etc? I don't think people should be getting merit for every report or something, but I don't see a problem with those who help out by making posts that help moderation etc.
