The thing about "only weak password accounts have to be reclaimed" is impossible, as the passwords are stored as hashes. Therefore MtGox can't know if a password was weak or not. So actually everyone needs/needed to reclaim.
I think it had to do with the likelihood that other people (the hackers) would be attempting to reclaim. If only one person attempted to reclaim a given account, then it is safe to assume that the password was strong and that the one person is not 'the hackers' (trademark).
I also fairly certain that no one else is even attempting to reclaim my account.
