Their definition is interesting:
Angle of Attack (AOA) – the difference between the pitch angle (nose direction) of the airplane and the angle of the oncoming wind.

I was never aware that the AOA measured wind; I always thought in 35 years of flying that it measured the angle of the oncoming airflow. To think I spent my whole aviation career with a misapprehension.
and it isn’t referenced to pitch angle either
