A second interpretation is that it tells the responder to forget what it has already sent, and re-deliver any status conditions that are still occurring.

As I said earlier, I prefer the second interpretation since it's a feature the standard really needs, but I don't think the text is clear enough.
Yes, that description is a bit terse. What is interesting is that it has been in since the original document and questions/issues have never come up about it before.

It is intended to pretty much do what it says which is to flush the status queue in the device. This is a SET message only with no other parameter data. So when a device receives this message it should flush all pending status messages it has queued.
