Maybe he's trying to encourage more sellers into thinking there's going to be a turn down so that the 'pop' is higher when he removes the fake offer. That appears to be the logic. However, someone with an offer 4 ticks away in not making a market and is wasting everyone's time. Whover he is, he can very quickly modify his price so that he's always 2-4 ticks away.
