what the document seems to say is this - you can accept your offer from Syracuse and then if you get an offer back from OSU, CU Boulder or UNL, etc., and change your mind about Syracuse - you can by notifying them in writing by April 15th (make sure its in their hands by April 15th - email and then mail with return receipt USPS). This may not make friends (in a small community such as ceramics) but its also your education.
The schools that are on the list seem to be large research universities - and their signing of the agreement has more to do with fields such as science and less to do with art - so thats why (I assume) that schools like Alfred, Cranbrook and RISD are not on the list.
