Carb depletion stopping the burning of fat? Well maybe sort of sometimes. Your author might be assuming everyone's a sugar burner. which many high volume fitness people are.
Imagine a person who has been a sugar-burner. If they go suddenly VLC, there's no sugar any more, and their body is not set up yet to burn fat. it needs different enzymes and mitochondria and what not. They aren't burning much of anything. This is the famous adaptation period.
Even a VLC person gets glucose from the extra protein so they're never zero glucose as this writer talks about. He might be assuming people are NOT adding extra protein for exercise, or that people aren't VLC or something. Notice he's talking about the ability to exercise intensely and long. Both of those require glucose.
A good source for understanding carb, fat for exercise is Mark Sisson
