That'a certainly possible. However, I was commenting on Rush's statement, which was a little different. Unless I read it wrong, he said that the UNLOADED vehicle would not produce more electricity descending the hill than the UNLOADED vehicle would use going up the hill. That's basic physics. If the mass of the vehicle doesn't change, the kinetic energy released in the descent can't be more than was stored in the ascent, no? If would be the same if the laden vehicle ascended and descended the hill. In the special case that the news piece describes, the mass DOES change. The extra kinetic energy descending comes from the load added at the top of the hill. Sorry for the confusion.
