I think I can guess what probably happened. Notice that the explosion happens when he touches the nozzle, and that he's moving toward it the nozzle, not away from it. I bet what happened is that he noticed some leakage from the nozzle, reached for it to shut it off, and when he touched the nozzle, there was an electrostatic discharge from his body to the nozzle, igniting the CNG. It can happen with gasoline, too - there's a Mythbusters video about it that I show to my chemistry students every year.
