I just don't see what problem this rig solves. It seems like a capriciously elaborate way to make a cat rig with a wire luff for a cruising boat. That eliminates the mast interference which is a non-problem in anything but very light wind with modern carbon spars. It does balance the sail plan on the mast which reduces sheet loads. Beyond that I can't see the advantage - and those were bought at great cost in complexity, and I fear, fragility.
