Actually, the quad could start at any point, so somebody doing it from scratch wouldn't necessarily even produce the exactly same file. If you compare 3068b with 3069b, you will see that 3069b chose a different point as the first point in its quad. (3068b starts at -X/-Z, while 3069b starts at +X/-Z.) Since the quad has to be CCW, the only thing an author can choose is which point to start with, but there are 4 options for that, and the fact that these two parts use two different options means that there doesn't appear to be a standard for which one to pick.
