If the heat is being generated by the friction of the grind, then I'd expect ceramic burrs to be much worse than metal. Metal would act as a heat sink and transmit generated heat away from contact with the beans by keeping the burrs cooler. Ceramic burrs are going to heat up and stay hot since they won't conduct heat away from where it was generated. The only place that heat has to go is into the next beans being ground....
Unless there is less friction with ceramic burrs generating less heat in the first place, which could be what was meant by the phrase you've quoted and disagreed with.
