Bingo. I got the PNR and called AS and asked the details.
The ~$250 is the difference between the cost of the outbound segment on the original AS ticket (~$325) and the cost of a walk-up one-way ticket on AA the same day (~$600). AS said they didn't assess any change fee, and they didn't reprice the AS return.
