It seems the doc hasn't been updated in the past 14 years.
Before 50a07e1, there was a single optional argument.
You might be one of the few users of this functionality, so maybe you
would like to fix the doc yourself?I don't use it myself, but I got a report from a colleague who interpreted the manual such that you could add ediff-janitor directly to the hook with add-hook. I've attached a patch to clarify this. I'll push it to emacs-25 in a few days until there are complaints.
