Recipe 1:

1. Emacs -Q
2. evaluate the following code in *scratch*:

   (display-buffer (get-buffer-create "aaa")
                  '(display-buffer-pop-up-window
                    (window-width . 20)))
   ;; => correct window width for buffer "aaa"

   (display-buffer (get-buffer-create "bbb")
                  '(display-buffer-pop-up-window
                    (window-width . 20)))
   ;; => changed and larger window width for buffer "bbb"


Recipe 2:

1. Emacs -Q
2. evaluate the following code in *scratch*:

   (display-buffer (get-buffer-create "aaa")
		  '(display-buffer-in-side-window
		    (window-width . 20)
		    (side . right)))
   ;; => correct window width for buffer "aaa"

   (display-buffer (get-buffer-create "bbb")
		  '(display-buffer-in-side-window
		    (window-width . 20)
		    (side . left)))
   ;; => correct width for buffer "bbb", but the window width of
   ;; buffer "aaa" is changed and becomes larger
