big bump in the rankings, the CFP committee will have to give BYU credit for beating them earlier this year and it'll hopefully make it easier for them to justify moving BYU higher than teams ahead of them as they lose
E.g. 2-loss Oregon lost to Utah while 2-loss BYU beat them (I expect Oregon ahead of BYU in the rankings, just using the example to make a point of how it could help BYU).
