If the pattern did work as you intended, showing the same buffer
simultaneously in two windows would not make sense: Whenever you moved
the cursor in one window it would move in the other window to the same
position.

It depends on what you want.  To move point in a specific window W use
(set-window-point W (point-min)).  To move it in all windows showing a
buffer B use

(dolist (W (get-buffer-window-list B nil t))
   (set-window-point W (point-min)))

Any of these will move the buffer's point if and only if W is the
selected window when you call `set-window-point'.  If you want to make
sure that the buffer's point moves too use

(with-current-buffer B
   (goto-char (point-min))

since the doc-string of `beginning-of-buffer' tells you
"Don't use this command in Lisp programs!" ;-)
