I wish that was how it worked, but my experience has been more like the parent poster's: long-standing easily reproducible bugs never fixed despite multiple reports and multiple major releases. I've never once been informed by Apple of a bug I submitted being fixed, or "asked to retest". Not being able to see the duplicate bug when your case is closed and marked as such feels like a slap in the face. I understand that some material could be confidential, but I would bet over 99% aren't. If someone has spent enough time to determine that my report X is a duplicate of Y, they could also determine if Y is confidential and if so, just flag it in the system to show up as redacted.
