He actually disappears if you've completed every sidequest he's involved in.

I know. The point was that, as long as you have not completed said quests, he keeps appearing there even if he is absent in the MSQ. So the argument that "quest givers can't die/change drastically" is invalid, in my opinion, because even if they are absent in the story, the game allows for these "time bubbles" to exist where the quest givers are still doing their job.
