But what if XXX-IAH actually cost more than XXX-IAH-AUS? Does the last segment have value, or not?
As part of the fare calculation and ticketing process, each segment is assigned a dollar value. (UA uses these values for PQD.) If you refund a segment due to irrpos you should receive the value of the coupon y

u are refunding. The amount refunded has nothing to do with the non-stop ticket price of the segment you just flew. In the example here, the generic fare is priced XXX-AUS. The fact that a stop at IAH was included is irrelevant.
