I'm going to agree with what the article is saying about doing weights before any type of aerobic exercise being the better route to take, but, disagree with the reasoning, specifically with the above statement.
When you exercise, your body needs energy and it needs it fast. the fastest way get that energy in use is to use the energy sources in your body that can most easily be broken down, and that would be sugar/glucose/carbs. using body fat as a source of energy while exercising just takes to much time.
That being said though, after you are done with your exercise session, then you're body starts using more body fat for energy in order to recover from that exercise bout you just went through.
So to summarize, while exercising, your body burns more of it calories from glucose/sugar/carbs than it does from body fat. After exercise, while you're body is recovering from what you just put it through, it burns more calories from body fat than from glucose/sugar/carbs.
