I don't quite understand the question but if I have to answer it then I reply that Michael described it the best.

"All is allowed and it doesn't matter how it is set or doused as long as the shape of the sail is correct."

And the only limits on the shape are the area, midgirth width and drawheight.

It doesn't matter when you fly it upside down, inside out, full of holes, from a bag, a snuffer or furl it.
