They weren't admitted, but how do you know they were not even considered?
More generally, a 1600 is not some kind of "get into college free" card.
I did admissions for a very competitive university program many years ago and we primarily used test scores to establish a baseline. One reason was to make sure we only considered people who could handle the program's rigour, but equally valid was that the four of us couldn't possibly review thousands of applications so we needed an automatic filter. But after that filter we didn't pay attention to test scores except as a tiebreaker when filling the last few spots.
