This sounds similar to the Double Round Stroke, which I was originally trying to link up to the image in question. If I were to make a guess, the image could show the preperation for the second cut:
Kind of, although the Round Stroke isn't described with the short edge. And the Round Stroke is a fast flowing combination where one can do 3 strikes for 2 steps with a slight pause with the foot in the air. However, the description from the 1560 doesn't seem to be as "flowing" and I get the sense that the ausnemen motions crossing center are meant to clear the opponent's weapon out of the way. There would be slight pauses in each of the Ochs positions, so I don't think the same footwork would work.
Jacob Sutor also has this illustration with the foot up in the air. But I'd need to go back and look at it to remember the context. I may have already translated that bit from Sutor as well. I'll try to take a look at it this evening and see if it sheds any light.
