Yes, I understood that, and at first thought that this could account for arrangement at the figure's left side, however having thought about it further, I doubt it can account for that either. The only way to demonstrate/settle this will be to attempt to recreate it, so I'm happy to agree to disagree until I can find the time to get hold of some sheets, and maybe a tailor's dummy.
