Price-wise you usually do
not want the domestic leg to be booked separately on a different PNR. I would think that it is irrelevant whether the PNR "sees" the international leg or not - the domestic segment stands by itself, even with the same flight number, so there are two "coupons" even though they both have the same flight number (just different origin and destination cities) and therefore the domestic leg should be eligible for the EUA. I will have to try it sometime if the situation arises.
