The plane averages the inputs. If you are pulling nose up six degrees, and Im an pushing down six degrees, the plane will be about nose level.
Remember, the design and intention of this aircraft, a multi crew airline transport aircraft, was based in the law/rule (and common practice) that only ONE pilot is in control at a time. Rather than letting the sysetm go ape if two pilots "fight over the controls" the aircraft system enforces electronically, via the flight control system, a disincentive to have two people trying to fly at once. That's not that bad of an idea, actually.
Since so much of the flight control movement is via computer, electronics, and hydraulic linkages, two pilots puttting contradictory inputs in at the same time could well break something.
That would not be good, when it comes to flight controls.
