It's possible that they sent it to all the applicants they are ranking to match, no? The secretary forwarded it to the distribution list, yet it was addressed to the applicant's name right?
They said something like "we would be delighted to have you as a resident and intend to rank you accordingly". I think that sounds like ranked to match. So congrats to all you guys!
(Then again, I've been known to over-analyze things.)
