I believe they also have a button to spit out current vote count for each candidate, obviously still possible for the code to detect when that button is being used a lot to check if it's counting properly. It's tricky because votes are meant to be secret (and voters aren't allowed to have proof of who they voted for, so they can't be coerced into revealing it), while at the same time you want the system to be secure.
