It doesn't immediately do so, though. Part of the ruling is that the status quo is maintained; there's no obligation for agencies to proactively remove regulations in response to how they guess some court somewhere might rule on a hypothetical lawsuit. So lawsuits have to be filed, first. So they will. Some of them may be resolved by the agencies just rolling over and doing the moral equivalent of pleading guilty, but if I know my principles of bureaucracy, that will be the rare exception, probably only so they can dedicate resources to some other more important lawsuit.
