While it looks like a clean way to run the wires I would worry about running the wires in contact with each other for any length. My concern would be "cross fire" or "voltage leak" into the adjacent wire. This is often called "induction". Where one wire "induces" a current in the other wire, one wire looses and one wire gains. Which doesn't do either one any good!

Perhaps not a problem with really good quality wires? Hmmmmm,,,,, maybe.
