Usually it's a portion difference, not a disagreement. This page scores ranch dressing at a serving of 1 tbsp; at 2+ tbsp (garlic/onion powder plus buttermilk) 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.
