I don't want to single anyone out, but I've seen this a couple of times: A moderator or someone with vote-to-close capabilities edits a question for clarity, spelling, or grammar, and also votes to close it. Does that even make sense?
The one exception I would see is if someone posted a "rant question" and you tried to edit out the rant to get the good question to the surface, and then the OP keeps reverting it back. In such "lost causes" it would make sense to have both edited and voted to close.
