Except that switch-to-buffer doesn't pay attention to it.  That's one of the
main reasons why switch-to-buffer should be avoided in elisp code and used
"only" via C-x b.

For the switch-to-buffer advice, the only alternative I know is to fix the
source code :-(.
But in order to show *...* elsewhere, all you need should be something like

   (add-to-list 'special-display-regexp '("\\*.*\\*" (same-frame . t)))

That's a bug.
