As far as I can remember, he will be able to use his protected ranking in 8 tournaments, which is about No.21 something. Don't know about the expiring date...
and if your ranking is 1000, you don't even have chance to qualify for the challengers events...but in his case, a wild card isn't hard to get.
BTW, someone left several messages in jjo.org and talks like Pim-Pim himself.I don't know if it's really him but if it was, wow.
Here's this guy's message,
