That's where the cleanup script puts them. It's something I've seen discussed by the unofficial patch team. It's basically to prevent NPCs from respawning, or as a workaround for various complications in Skyrim's quest and scripting systems. The developers often built very kludgy workarounds for their own problems, that they theoretically could have fixed at the source, because they were the developers. Left hand doesn't know what the right is doing sort of thing.
