It (the one-flight-number for two segments) works both ways (for and against you):
* yes, you loose miles, as you will only be credited the direct (fewer) miles.
* if you fly on a ticket that counts miles (example StarAlliance rtw) you will 'only' be calculated (it costs you only) the direct (fewer) miles
* if I use a visit US-coupon on N-American UA-flights, I must only redeem ONE coupon per FLIGHT Number (and so profit from that same flight number for two segments).
