Previously, setting aside the temporal distortion, which I agree should be fixed, the intent was that if there are *any* unblocked signals, one of them gets delivered. The proposed wording requires that one of the signals that became unblocked by the call be delivered. This makes a difference if some other (unblocked) signal just happened to arrive during the system call, which unblocks some other signal, the system is not permitted to deliver the newly arrived signal, but must deliver one of the ones that had been blocked. I don't think that change is really intended. I'd keep it simpler, something like Before the pthread_sigmask() call returns, if there are any pending unblocked signals, at least one of those shall be delivered.
