There's another case in the Rules Forum where a moderator has been the principal poster in an argument, and at the end of the discussion has pulled out the moderator hat and locked the thread.
This has become fairly common and I think it's objectionable. There is a significant "conflict of interest" when a moderator promotes an ongoing argument for an extended period of time, and once people get sufficiently aggravated, shuts the thread down to further responses.
My recommendation -- Have a policy where mods do not moderate (discipline or close threads) in a thread where they have been a discussion participant. (Consider other sites like Slashdot that exclude moderating and posting in the same thread.) This would help solve the significant "conflict of interest" problem in these situations.
