Getting confused here. Isnt it reported that MCAS only uses one AoA vane? If there is a disagreement, what does it matter if it relied on one? Add-on alert or not, didnt MCAS only use one?
Lion air flight had an AOA disagree of from memory of 40 degrees on the ground and in flight. So with this disagree warning the flight would not have happened - the fact the LH AoA was in error that would have activated MCAS then becomes irrelevant - the flight would not have happened.

NOTE - my understanding is that the LH aoa on Lion Air read 40 degrees different to the RH AoA in every position stationary or moving.
