From that article... they are doing twice-weekly testing of all students but they are still having to do a lockdown for two weeks.
"For the next two weeks, the university expects all undergraduate students, for their own protection, to significantly restrict in-person activities. From now through Wednesday, Sept. 16, undergraduate students should avoid gathering in small or large groups under any circumstances. They should only leave their residences for essential activities including taking twice-weekly COVID-19 tests, attending class, purchasing groceries or food, going to work, engaging in individual outdoor activity, attending religious services and seeking medical attention."
