With half slopers (wire length = quarter wave electrical) disconnected and 
unused, they act like "nothing" for RF at the frequency of operation. This 
"trick" of disconnecting quarter wave radiator (wire) from the ground 
connections is used to disable the vertical, detune it from the resonant 
frequency = make it "invisible" to RF (at that frequency). 
For wire like that to act as a "counterpoise" it has to be connected to the 
antenna system or be near half wave electrical length to act as a parasitic 
element and be positioned so it can direct the RF from the radiator in the 
desired direction. 

How are the unused slopers "counterpoising" the RF from connected sloper?

When W8JI "gospel" is questioned, there is usually twisted runabout answer or 
dead silence. 
If TT likes to be fed this stuff, it is fine with me, I just have a problem 
swallowing some of the statements that are not founded in reality.
