"What we can do in our airplane is get above the Mach with afterburner, and once you get it going ... you can definitely pull the throttle back quite a bit and still maintain supersonic, so technically you're pretty much at very, very min[imum] afterburner while you're cruising," Griffiths said...."

So, dressed up in a load of (undeniably authoritative) fluff, it can't supercruise. Which was what LO said.
The increase in fuel burn from max dry power to min afterburner is significant.
