Yes, the wheel and its indicators become (almost) irrelevant once you use the azimuthal controls.
The steering console should have been far enough from the manoeuvring station to prevent a quasi simultaneous use of both modes.
If you set for instance the rudders 15° left with the wheel, and then change one of the azipods orientation, the direction of the other pod will remain at 15° until you change the direction of both with the wheel, or with its own azipod control independently from its twin.
If you change your mind while the pods are pivoting, you could easily lose the oversight of their positions during a short time, not knowing how to interpret the readings. That is why it is advised -absent a mode selection repeater- to avoid jumping from mode to mode without having reset the wheels, controls and pods to midships in an orderly fashion.
