It should do, but the alert logic currently expects all landing gear on ground before the thrust reverser starts to deploy. This is out of sync with the aircraft thrust reverser logic which expects just the main landing gear on ground.

Sorry, I didn’t write that very well. We would delay unwanted alerts whilst the main landing gear is down but the nose gear is still airborne (aircraft “in air”, thrust reversers deployed). Once the nose gear touches down, the alert logic finally considers the aircraft on ground, and at this condition (on ground, thrust reversers deployed), there will be no alerts.
