Perhaps one should say "modeled" rather than "predicted", since they already knew the explosion had occurred. It was just a question of when the light would arrive by the fourth pathway (if I'm reading the article correctly), which required modeling the approximate mass distribution of the lensing cluster from the three images already in hand.
