Wrong, as at the start of the enclosing form.
well, "defun" here actually means "top-level form";
the command works w/ all kinds of sexps, whether or not
they are actually `defun's.
`defun' is a special form with a special meaning in emacs-lisp

Think it's disturbing to introduce a different meaning employing the
same name.
This pertains to the Emacs Manual were is said

A `top-level-form' might be a defun, but is a far more
general terminus with his value at his own AFAIU.
Certainly a function `beginning-of-top-level-form' is
useful. However, it should be callable separate from
`beginning-of-defun' and vice versa.
the way to make the behavior arbitrarily more precise is
to customize `beginning-of-defun-function'. for example,
see `python-beginning-of-defun' in progmodes/python.el.
`beginning-of-defun' should work right out of the
box at least in Emacs Lisp. That's easily to be done -
if the need is recognised so far.
