I think that behavior really depends on how your UAC is implemented internally. For example the SIP stack could eliminate duplicate 200 OKs in processing queue before they hit transaction logic/UAC. Therefore, UAC core may not even see some of those dupes. IMHO such behavior while not exactly RFC-abiding is permissive and is unlikely to create any issues.
