Interesting.  I agree with what it says about drying marinated meat - easy to get bacteria, and it won't last long.  They sort of touch on cured meat, but not really.  
Personally, I have no fear of jerky strips brined in a cure (with #1 Instacure), then smoking/drying at 140°.  The curing salt kills virtually all the bacteria - sausage makers have known this forever, and they don't "precook to 160" before drying.  If you cook jerky strips to 160, and then attempt to dry further, I think you'll have jerky that more resembles fried bacon, but I could be wrong.
