I would say no also.
Do you see how it is made? You assemble two strips with a shorter cross-strip at the end; make 4 of those. Then sew them on to the center square as if you were making a log-cabin. Only thing is you have one extra short seam to sew at the end.
Clever. Think I will bookmark this one.
Edit: Actually, you would have to sew each component to one side of the square first, then go around and finish the 4 seams. Still would be easy to do!
