If you are referring to changing your password the first time you logged in after the breach, then what is happening is that PSN knows you created that account on that PlayStation, hence the lack of confirmation. I created my account on a friend's PS3, and when I signed in I got sent an email which contained a password reset link. It's rather strange then, given how secure the reset process was post-hack (and I think they did a really good job of making it secure and convenient) that they left such a gaping and obvious hole!
