No, because the NSA directly collecting the information under PRISM doesn't mean that the FBI won't also be issuing NSLs, under more specific justification, for information that the NSA already happens to have.
Just because the NSA has it doesn't mean the FBI has access to it.
Still doesn't seem very transparent. It's kind of like saying that I didn't drink any alcohol today, but I might be doing an undisclosed amount of drinking with my friend Ned. Kind of defeats the purpose.
