Only if they really “stand strongly” and give higher scores to such views and it's not just marketing. If they advertise about social justice, but the admission process is in fact pretty conservatives, this posture will not have a dramatic effect.
But anyway, even if this is true, that doesn't mean that it's the current Elite's views, just likely to be the future Elite's views (assuming that higher education pays a significantly higher role than the set of other Elite's beliefs they'll encounter later in their lives and that they'll mimic too in order to be successful later, since the process you're describing occurs over and over and over in someone's life).
