There is no guarantee that my suggested change gives better results than 
your original script. I suggest you try both and see.

That won't actually change anything at all. You are still calculating 
the energy for each residue individually. If you wanted to calculate the 
energy of the pair of residues simultaneously, use something like
(s|s1).energy()
The same disclaimer from above applies.

randomize_xyz simply randomizes the coordinates, with no consideration 
of steric clash etc., so it will make no difference whether you 
randomize both residues simultaneously or one at a time.
