Allow me to disagree with that... 

I agree with @Krikor, I read the manual... twice (second time very slowly) and still don't picture out the full process  
I think it's the way you wrote the manual, IMHO you give too much info while explaining, thus I got lost.
Also you speak about portrait mode but images and paths are horizontal in your example (thus my second read), should the path not be vertical on these landscape images?

I'll try tomorrow when I will successfully decode the whole thing in simple steps,
something like
step 1 scan that paper,
step 2 put upside down that paper and re-scan it,
step 3 import in GIMP
step 4 in the layer stack, which one I put on top? the second scan?
...
step 99 save as xcf as we can use it as template for future scan
 

Well, I've always had a hard time understanding most of Ofnuts' explanations.
Many, many times I read and reread his instructions in order to finally understand them.

I think perhaps because of his genius he lacks a little empathy for less evolved minds. Something like Einstein explaining the theory of relativity to teenagers the same way he would explain it to his fellow scientists.

Adding to that the language barrier (English is a hieroglyph for me :-)), I often feel like I'm solving puzzles.

Note: I initially had difficulty understanding this sentence:

"(always per inch, even if the units beloware millimeters)"

But it seems to be not an unknown word in my vocabulary, but a combination of below+are

PixLab, I confess that I was very relieved to know that you also found some difficulty in understanding this document!
