Accepted President's scholarship ... does that mean I accepted the admission as well?

DS received early admission in Computer Science, with President’s scholarship.
He is not sure whether he will go to UMASS or some other school, as he is waiting for decisions from other competitive schools

But, in UMASS SPIRE system, he did the mouse clicks to accept the President’s scholarship and federal unsubsidized loan

Question is: does that mean HE HAS to ATTEND UMASS?
DS is getting concerned

His thought/assumption was that: if he does not want to go to UMASS, then these “scholarship acceptance” will simply become VOID … but now he is very concerned

Could some of the knowledgeable experts share your knowledge/throughts?
