One advantage of this is that there will be no current flow through the 
wipers connecting the rotor to the frame.  I presume that, especially if 
it's an old capacitor and the wipers aren't in top condition, the normal 
connection will have a certain amount of loss (= heating) caused by the 
tank's circulating current.
