The EFF really should do a better job of explaining what this means in practice. Their last paragraphs hint at it, but they should make clear that in practice the government has access to all the data it used to, because the authorizations of the NSA are overlapping. It would be like if a city block had 20 CCTV cameras on it and 2 were taken down.
More importantly, these records are but one item in the enormous dossier of each person on earth.
