I'm paraphrasing, but the entire messaging campaign is that everyone needs to follow guidelines exactly. I'm sure they do not count on 100% compliance but they are projecting an extremely optimistic view, here on campus and in media they are publishing. This incident exposes weaknesses in the plan: (1) it was an off-campus student, who the administration "hopes will do the right thing" - and that is close to what was actually said - so there is no testing or tracing requirement aside from whatever VDH might do, and (2) the student did not follow what was asked of them, to quarantine for 14 days before coming to Blacksburg, literally traveling from a hot spot without isolating first.
