In the section/visualization "Backward Overview", the top derivative is with respect to b and the bottom is with respect to w. But in the next section, "Backward Computation", the derivatives (with filled-in values) are flipped in the box. The labeling below the box shows the correct output, but it might be clearer to have the derivatives in the "Backward Overview" section be w then b, so that everything matches up more cleanly.
