I think his point is to put all the heat on the one disc. Thus if it begins to fade, you've got a front caliper that has little or no heat, and is perfectly adequate to stop the bike while the rear disc cools.

If you're dragging two disc brakes on the straights, you risk fade to the point of inadequate stopping power, and have nothing left in reserve.

Also by putting the heat to the rear disc, you're not risking a front flat from heat from the rim brake.
