The reason is that the initial frame is not made by 'make-frame'.  The
Elisp manual says

     Note that any functions added to these hooks by your initial file are
  usually not run for the initial frame, since Emacs reads the initial
  file only after creating that frame.  However, if the initial frame is
  specified to use a separate minibuffer frame (*note Minibuffers and
  Frames::), the functions will be run for both, the minibuffer-less and
  the minibuffer frame.

This explanation is slightly misleading: Since the initial frame is
not created by 'make-frame', Emacs would not run these hooks even if
it did read the initial file earlier.  Hints for improving the
documentation are welcome.
