After you do a vigorous or long workout, your blood and muscle glucose will be much lower than before you started. Low glucose stores signal the body to burn fat preferentially. So after hard exercise that uses a lot of glucose, the body switches to burning fat. That's why all energy expenditure is important, not just fat burning during exercise.
And as you get fitter, your body's ability to burn fat will increase, and so will the intensity at which fat-burning is maximized. Here's a graph from that Spanish study, showing whole-body fat oxidation in the heat for trained and untrained subjects, as a function of exercise intensity:
