After drawing the triangle on the pieces that were in their correct position, you can separate the pieces, do whatever you need to them and then put them back together in their original locations by putting the drawn triangle back together correctly. I've never done it as they showed but it works great for marking the locations/order of multiple boards being glued side by side like a laminated strip cutting board though I only use a 'V' or teepee shape.
