As yet another Sign of the End.
This, for a while. Once it becomes obvious that the prophesy is bunk, they'll stop talking about it (ala king of the north) for a while.
Based on the current trends, this cult is moving away from trying to construct semi-logical interpretation of prophesy, and moving towards being based solely on emotional manipulation and groundless "armageddon is comming soon" statements. So in line with that, I don't see them trying to re-interpret the prophesy so that it'll make sense.
