In that case, we're both at "beginning of defun" and at "end of defun",
so we have conflicting requirements.  But I think it's clear that
(end-of-defun -1) should move backward if possible, so it's more
important to consider that the position is "at end of defun" than "at
beginning of defun".

IOW, yes, we have a bug.
I installed a brute force patch for it,
