But it's not supplementary bonding.
Why can't you understand that?? The steel wire is not an extraneous part. For starters it's not part of a non-electrical condition because it's part of a cable!! Your not using the fly to bring it to the same potential your using it to earth the cable.
It's the same concept as having an earth wire in a bit of twin and earth. Can't get clearer than that.
