Failed loft /Ruled surface in grasshopper

Hi ,
I am trying to loft from curve to curve (of face to face) but it fails , although I have adjusted the curves seams , even ruled surface has failed ? any advise .

The curves had different tree paths so they need to be flattened for the loft to work:

Flipping the direction of one of the curves seems to do the work:

I would also say that this same result could be achieved by extruding the curve you already have instead of using the “Offset Surface” component, which leads to the rather complex script you have going on for this simple purpose.
