I highly doubt Yuri was correct about people who commit suicide can't go there. Heck, she didn't even know of the Afterlife School's existence until she died. She probably assumed it since none of the SSS members had killed themselves so she probably thought so.

It still remains a mystery on how Yuri and Naoi died. Not even the manga gave us any clues.
