They use ranked choice voting so this shouldn't matter, as far as I understand RCV eliminates the lowest option one-by-one, passing the votes to the next option on each ballot as if the eliminated option never existed.
The discussion seems to be about ballots with 3 > 2 > 4, and when 3 was eliminated the votes went to 2, allowing it to pass. That's a bit strange because you'd expect a ballot to always have 3 next to 4 since they are so similar.
