AA accepts the responsibility for a misconnect and thus sets the MCT. Whether that is within SCT (Sensible Connection Time) is a matter for the individual.
AA has four nonstops to MCO as well as inumerable other connections. Thus, a misconnect should not be a significant problem.
However, looking at the AA website, I don't see the LHR-IAD/DCA-MCO on offer. This leads me to believe that some TA has put together a package of some sort which includes separate tickets or some form of forced stopover. Those passengers will hopefully check their e-tickets carefully. AA does protect across separate tickets, but they will have none of the other benefits of an EU departure, e.g. EC 261/2004 as to a misconnect.
