You'll notice they explicitly don't cover regulations (like the one they were writing), probably because of the amount of legal precedent for nitpicking the exact phraseology of a given law or regulation...

No, they were writing a law, which is different from regulation; law isn't covered, but not because it is explicitly excluded, but because its not included, at a minimum because it is written by Congress, and this only covers work product of Executive agencies.

But more importantly, they've specifically acted to make the law completely unenforceable (see Sec. 6.)
