The relevant part of the podcast starts at 10:50. My understanding is that because the pigmented regions are more efficient at heat transfer (either as net radiators or net absorbers, depending on time of day and incident radiation) any change in the volume of blood directly beneath them has a greater effect than changes under the lighter regions.
In other words, you get a bigger “thermal lever” from the same effort spent on shifting blood closer to / further from the skin by doing it specifically beneath the pigmented regions.
