I didn't get the impression that Snowden actually has access to PRISM itself. If all he's doing is IT support then it could be as simple as that he ran across the "management briefing" for it on the share drive without ever having access to the system itself. Certainly I would hope that NSA is not dumb enough to farm out credentialing for a system like PRISM to one of their contractors, but who knows?
