It cannot be a named selection. This is a weak spot in PyMOL. Coloring two strand differently of a double helix makes it easier to for the viewer to distinguish the two strands. Many double-stranded helices have one strand in the asymmetric unit. The second strand is in the biological unit. The coordinates for the second strand are in the pdb1 file type at the PDB.
