 I don't recall a TSB for the wire, so I would guess it was a running change.
Since it cost money to add it, I would venture that it was determined that the single wire did not have adequate capacity which would cause it to get hot and be a potential fire hazard. You could replace the single with a larger wire if running two wires bothers you.
