Usually it's a portion difference, not a disagreement. This page scores soy milk at a serving of 1 cup (250 ml) if made from soy protein; at any serving if made from whole soybeans 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.
