Yes, but did they change the meaning of grounded conductor in the NEC?
230.42[C] says minimum size and rating of the grounded conductor.

It looks like what they are getting at is that if the unbalanced load calculated in 220.61 results in a ampacity of less than the conductor sized in 250.66, then that then becomes the minimum size for the grounded service conductor. In essense it appears they are saying that the grounded/neutral conductor can't be smaller than the grounding conductor.
