Probably. It would appear, however, that there is that sort of timer system in place as a backup. It is possible, if a bit unintelligent, that they would begin to rely on that backup instead of designating another Vanguard. The Vanguard system failed, after all, so they might not want to use it again. For all we know, they could do something completely different.
