Jeff Hardys last show with the WWE will be the tv taping on Smackdown. So, Jeff will be in WWE after Summerslam but, for one show. Also, keep in mind, Jeff plans on returning after his hiatus, so if he did leave he'll return in MMX (2010) thus meaning he will be in WWE after Summerslam. Matt never said he wasn't leaving, he just said he'll be with WWE after Summerslam.
