Well, that's no longer the case. The security checkpoints for INTL and DOM flights have been merged. This means that everyone clears security in the same area irrespective of their destination. If you are flying abroad, you then turn left to clear customs and immigration and if you fly domestic, you turn right and clear.... nothing.
One can, therefore, spend some time in the domestic departures area before clearing customs & immigration and proceeding to the international airside area.
