Because SDL hooks the keyboard input at a low enough level that it receives the keypresses before the window manager does.  <ALT>-<F4> is defined as a menu shortcut for the Close command in the window's system menu, and then the Close command generates a WM_DESTROY message.  But since the window manager never gets the keypress, the shortcut can't be activated.  (Opening the system menu with the mouse and selecting Close works just fine.)
