The first problem is in the docstring:

  It finishes by running the mode hook variable `MODE-hook'.

this repeats a very widespread misconception, which is that those hooks
are variables.  They're not: a hook is a symbol, not a variable.
That's why it can work even if the variable by that name is not bound.
