True again, I guess in my mind I had imagined the locked/non-swiveling caster-style wheels.

Swiveling caster with an encoder will only track total distance traveled from starting. Unless you track wheel spin and another encoder of the orientation of the caster. Which may, in fact, be what the poster meant originally and I misunderstood.
