Then what about
    M-: (display-buffer "*scratch*" nil t)
which does indeed select the window on the other frame and switch focus.

While it is documented as
    (display-buffer BUFFER-OR-NAME &optional NOT-THIS-WINDOW FRAME)
    Make buffer BUFFER-OR-NAME appear in some window but !!! don't select !!! 
it.

Whereas 'select-window'
    (select-window WINDOW &optional NORECORD)
    Select WINDOW.  Most editing will apply to WINDOW's buffer.

does NOT select the window to apply my editing.

What are the intentions you see and how do they make sense to you?
Just curious ...
