I've made a couple of G-4 packs but don't recall these particular steps. I don't have access to my instructions just now; I'll look later today if I can remember. Could you elaborate a bit on what you are trying to do with these two steps? I don't recall the mesh pockets as being particularly complex other than the possibility of winding up with the tie loops inside one of the pockets. I did that once; I spent some time muttering IIRC.
