So what you're saying is that if the relative airflow is symmetric (i.e. parallel to the fore-aft axis of the aircraft) but the rudder is providing a lateral force because it is non-central, then you...

Ah, perhaps this is the cause of the crossed wires.

If you hold the wings level and use rudder to correct the asymmetry, the aircraft will slip towards the dead engine.

If you use wing down to...

I would interpret the word yawing to mean having a component of angular velocity about its yaw axis. An aircraft in a perfectly balanced level turn is therefore yawing (as well as pitching a little).
