Not really. Data from two sensors is not sufficient to determine a value. It can be sufficient to decide whether to use the information at all. That decision can be automated or manual (e.g. requiring the pilots to decide). In this case it wasn't automated. The fact that the indicator (AoA disagree) necessary for pilots to have the information was sold as an option is pretty terrible, though.
