I think that is right. I've seen this happened. currently once I vote for one thing and my larva passes once Maine, the second vote gets in to cancel my 1st vote. It did not use to be the case. The larva accustomed skip a post I already had voted on.

I'm undecided however it happened for you that you simply were ready to cancel your alternative vote while not truly cancelling it however that appears to be what happened.
