I did not say that was the only reason. Just that, IME, it was usually an indication as to which side the separate shield wire was grounded to.
In my designs I have stayed away from a separate shield or drain.
Lastly I'd not be at all surprised if it does make a difference for some little known reason. If you have a favorite "directional" cable what is it, for I am always willing to try new things.
