The doubt raises the fact that evaluating the expression after
selecting " *Marked Files*" was intentionally coded this way
in `dired-mark-pop-up':

               (with-selected-window window
                 (unwind-protect
                     (apply function args)
                   (when (window-live-p window)
                     (quit-restore-window window 'kill))))

I guess the reason was to allow quit-restore-window to kill the
" *Marked Files*" buffer after the minibuffer (that reads a command)
is displayed and exited in `(apply function args)'.
