Even if they were together I feel AA books Etihad tickets different, because I had a flight from AUH to SYD, and wanted to add on a segment inside Australia and they said it was additional miles. So not the same as their normal ticket.
That would likely be that EY did not offer fares to that domestic location which allowed travel on an airline that is a partner of AA
Not only does it have to be a valid airline for awards, but the governing carrier has to have a fare that is valid for the itinerary
Taking LHR-ADL as an example, EYs fares require that the domestic sector be on EY ( codeshare ) or on VA . Since VA is not a partner of AAdvantage that will stymie booking the domestic leg
