The difference shows up at audio frequencies and for lightning. Coax
between gear is usually longer than needed for bonding -- that is,
dedicated bonding conductors can be shorter, thus lower inductance and
resistance. See the slides that address audio buzz from power line
leakage currents. At AF (and for lightning), bonding is a band-aid for
Pin One Problems that is present in virtually all ham gear, computer
gear, and audio gear.
