I don't see a problem with that doc string in particular.
What did you have in mind?

This part is a little unclear:

"The value of `normal-auto-fill-function' specifies the function to use
for `auto-fill-function' when turning Auto Fill mode on."

One wonders why it speaks of `auto-fill-function', as if it is something
understood  (begs the question of its relation to `auto-fill-mode').

If you then click the `auto-fill-function' link you get doc on that function,
but it's not clear at all what it has to do with `auto-fill-mode'.

It does say also this: "auto-fill-function is also a variable."  But the name is
neither quoted (`...') nor a link to help on that var.  And there is nothing
saying  anything about what you said: that the variable tells you whether
`auto-fill-mode' is on (which was the OP question).

Perhaps we should at least add something like this to the `auto-fill-mode' doc:

"When `auto-fill-mode' is on, variable `auto-fill-function' is non-`nil'."
