Nope, it's not clear.  The doc of `add-hook' does
not at all talk about buffer-local functions.  It
talks about buffer-local hooks and a buffer-local
hook list.  A buffer-local function is neither
defined nor described anywhere.

If what is meant is the use of the function on
a hook buffer-locally, then say that.  Don't imply
that there's such a thing, defined anywhere, as
a buffer-local function.  Or else define it
somewhere.
