The two sticks can be pointed in different directions. The plane does not complain about this and averages the inputs. One pilot is pulling back, one is pushing forward, plane crashes. Clearly there are some human factors here, but from what I've read, on Boeing's aircraft pushing one stick causes the other to move, much more intuitive.
