Suppose the election ends, and it's time to verify the seals. Oops, they are broken. Now what?
All the seals can do is cast doubt on the results. You can't bring back the voters to try again. Even if you could, time has passed and they might vote differently. You could toss out the results, but that affects things too.
If you toss out the results, an example attack is: break the seals in areas with undesired voters
Similar attacks can be done if you call voters back. Maybe this allows for more-favorable hours or different media exposure.
