Usually it's a portion difference, not a disagreement. This page scores white sugar at a serving of 1 tbsp (around 12-15 g); at very large amounts where total fructose load rises it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
