Each oval should precisely line up with the the horizontal timing marks. Thus any fold/crease/score through a timing mark IS a fold/crease/score through an oval, and is to be avoided.
I realize that won't give you any higher confidence in whether or not your vote counted. Ballots with folds through timing marks, and thus through ovals, were likely folded improperly. On the other hand, if the ovals and the timing marks don't line up, then they were not printed to spec. Neither problem is of any good to a voter.
