<p>I’d say there is little hair-splitting available here. </p>
<p>After years of controversy, the consensus has become that applicants can “walk away” from an ED offer of admission, but only for a lacking financial aid issue. </p>
<p>A candidate who did NOT apply for financial aid cannot use that joker card, and can only be released at the discretion of the school. </p>
<p>In the case that the candidate plans to attend and accepts the offer, the next step is to notify all schools of this acceptance (meaning of withdrawing applications) and be left with the sole and only ED acceptance in hand. </p>
<p>On a practical note, the ED schools could not care less about the rolling admission acceptances, but the question is why would anyone keep those applications/admissions live! Your best bet here is to call the ED school and ask them directly.</p>
