The reason for this is because in outline mode, headings are starting with
a number of stars, while in Org-mode, they start with stars followed
by a space.  So "***News" is a heading in outline-mode, but not in Org-mode,
where you'd have to use "*** News".
When outline-mode tries to invent a new heading during demoting, it replicates
the last character in the headline marker, and that will be a star in 
outline-mode
and the space in Org-mode.

We could fix this by defining outline-headling-alist in org-mode.  For example,
you could do it like this:


(add-hook 'org-mode-hook
   (lambda ()
     (setq outline-heading-alist '(("* " . 1) ("** " . 2) ......))))

and make sure to mention all levels you might possibly every use.
However, Org-mode is not outline mode, and there is no guarantee that
outline functions will work.

Another option, if you prefer the C-> and C-< bindings is this:

(add-hook 'org-mode-hook
   (lambda ()
     (define-key org-mode-map [(control ?<)] 'org-promote-subtree)
     (define-key org-mode-map [(control ?>)] 'org-demote-subtree)))
