Yea, I would think continuous rotation. Your gut is correct, you probably won't find many recommendations for using potentiometers where encoders are more appropriate.

You don't need to measure position (absolute) of your wheel, you can get a software based dynamic brake by using a PID-based velocity control algorithm, and setting the desired velocity to zero (this would be a side effect of the driver letting up on the joystick). Eh, I think this is what he was talking about anyway.
