From my readings, I don't think it was a central doctrine. Here's the relevant writing from Berg: http://pubs.xfamily.org/text.php?t=156 http://pubs.xfamily.org/text.php?t=156 He seems uncertain about it and couches it more as a possibility. The prediction is actually a timeline of world events involving the Antichrist that begins in the 1970s, so they would have known decades in advance that it wasn't coming true. Certainly by 1986, when Flor Edwards says she was thinking "I would be twelve when the world ended [in 1993]", they would have noticed that the Antichrist hadn't created a one-world government as predicted.
