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.
