It's saying that there were two pure and nonoxidized samples, the two Mexican refined oils.
There were no "extra virgin" samples that were both pure and nonoxidized, though of the pure extra-virgin samples, the CalPure one was the least oxidized. They had 2 samples that were low oxidization but were apparently roughly 100% soybean oil.
