is that it's probably not that they won't take a kid with a 32 and a 3.8, just that it's not longer the only thing that matters. If you have to candidates that are literally exactly the same (same HS, same ward, same extracurriculars, same interview scores, same score for admission essay, etc) but one has a 32 and a 3.8 and the other one has a 29 and a 3.5, BYU is going to take the kid with the better academic profile. But if the 32/3.8 kid has nothing else on their application, and the 29/3.5 kid has all the other stuff (seminary president, soccer captain, 4h, spelling bee winner, whatever), they might take that kid instead.
Now I might be wrong. Maybe they fill up a certain number of kids at the top and then just randomly admit a bunch of other kids with worse scores for no reason other than to keep BYU from having too many nerds, but that seems unlikely, unless this gif is your new Dean of Admissions:
