The text referencing Figure 2 seems to mistakenly swap the top and bottom images.
When the legs are in the reverse recovery position (fig (fig2,2, bottom), the penis lies on the lower thigh and is protected. In this position the Achilles tendon of the leading foot can be inserted in the gap between the big toe and the first lesser toe to help correct a bunion.
Note that the top picture in Figure 2 shows the Achilles tendon of the leading foot between the big toe and adjacent toe of the trailing foot. I would conclude then that the top position is actually the one that protects the penis.
Figure 1 also has the images the wrong way around, though it's harder to see because they're meant to be side-by-side. I think it's a problem with the HTML conversion.
