Yes, that happened to me. I purchased a round trip ticket. Upgrade offer was showing on both outgoing and return segment on my reservation. I called AA to look for a mileage upgrade. Milage upgrade was only available on outgoing flight, and not on return flight. I took a mileage upgrade on outgoing flight. After I did that, there was no upgrade offer shown on the return segment of the reservation. I thought the upgrade offer on the return segment will reappear later, but never did.
