My guess is that it'll be used to highlight meaningful differences between applicants' scores. In other words, if two candidates have different scores, but the confidence intervals overlap for the scores, you can't conclude that there is a statistically significant difference between the scores (if the intervals don't overlap, you can conclude there is a statistically significant difference between the scores). When the intervals overlap, admissions should treat the scores as being not different from one another. Whether or not schools will utilize this or not is another question.
