To that end, I could see the point if the OP doesn't care about a seat or upgrade on SEA-PDX but does on PDX-MCO, why pay an extra $20 on SEA-PDX if the fare is calculating that way?
It would appear the OP doesn't want to pay a main fare on a QX400 if saver is available. The through fare is usually cheaper than each segment priced independently and AS will calculate the through fare as already stated.
It is also published that Saver fares cannot be combined with any other fare type so the discussion is really moot. An itinerary is either saver or not. The only way would be to purchase two separate one-way tickets which in most cases will be more expensive than the through fare whether saver or main.
