In X you can never be sure.  You can request a frame change but it can 
be denied.  For example, fullscreen or tiling window manager.  There 
should be no assumption that what Emacs request w.r.t. frame size 
actually occurs.

No, the window manager denies the original frame resize.  There is no 
"resizing back".
