`auto-fill-mode' uses internally `auto-fill-function'. I don't recall
the details why it had been chosen to design it like this. But yes,
it's possible that a mode uses a variable of a different name for
toggling.
Part of the answer is probably that different auto-fill functions can be
used this way, and for all values besides nil the mode thinks of itself
as "on". OTOH, setting `auto-fill-function' nil automagically turns the
mode off.

AFAIR I also already gave her an answer, hope it has arrived.
