It doesn't work. Not possible to swing with a FLW Backstroke and Downstroke, with 10-20-E and Horizontal Hinge. Incompatible with 10-20-E. I wouldn't agree under torture.
Swivel Startup, Swivel to FLW/BRW during Release. Let the Force be with you.
I'll admit that with 10-2-F it worked a little bit.
