No, you are the one mixing things up and assume stuff. There is no active nose wheel steering. The nose wheel is pivoting freely.
@Everyone that care
If you MUST apply brakes in order to turn, then the model is wrong in the current state. But IF a movement of the rudder actuate the brakes (both), and venting the opposite cylinder. The current implementation is correct, and explain why the aircraft behave like it does.
