Do you mean that

(with-temp-buffer
  (let ((buffer (current-buffer)))
    (select-window (selected-window))
    (message "before %S after %S" buffer (current-buffer))))

is surprising?  But 'select-window' only does

  In addition, make WINDOW’s buffer current and set its
  buffer’s value of ‘point’ to the value of WINDOW’s ‘window-point’.

as advertised.  Or do you mean something else?
