Usually it's a portion difference, not a disagreement. This page scores diet cola at a serving of 1 can (375 ml); at versions sweetened with sorbitol/other polyols (then Sorbitol) 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.
