The only thing I can think of is that the person setting it up might 
have planned for additional virtual interfaces.  Or maybe that's how he 
learned to set it up. 

Regardless, if it works, it works.  It's just not the best way to setup 
a single bonded interface, IMO.  It's adds an additional layer of 
complexity that doesn't need to be there.  Like I said earlier, I have 2 
machines that have bonded interfaces with virtual interfaces on the 
bonded if.  It's not setup like that either.  Bond0 is the primary IP, 
and the virtual if's are Bond0.1, Bond0.2, etc.
