I think s/he's talking about still-valid paper certs that someone might have. In the paper cert case, I imagine you use them like you would always use them. If you cancel the ticket, the paper cert would still be valid until it expires. I don't know that they would re-issue it as a electronic certificate, but either way, you would still have a valid BXP1.
