If you quoted, then at least can mean a lot. There could be something in the agreement that provides for an extension, or opens it back up for Microsoft to make a move. So it could be that Sony has extended the agreement but possibly not updated their own page, as they seem to be network challenged given the rigidity of PSN, security issues, and technical issues. Or it could be that updating that just isn't a priority. It could also be a Bungie typo, or only be about current exclusives which they many consider y2 ones to not be current anymore. But all of that is just speculation. Bungie and or Sony are the only ones likely to have the facts.
