Why

The ordering also runs the other way acoustically: the highest vowel has the lowest first formant, near 300 hertz, and the most open has the highest, near 700. That inversion is why acoustic vowel charts are drawn with F1 increasing downwards, so the plot resembles the articulatory quadrilateral.
