Usually it's a portion difference, not a disagreement. This page scores mashed potato at a serving of 1/2 cup made with lactose-free or plant milk; at high if made with large amounts of regular milk/cream or garlic 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.
