The diagram above shows that each choke coil performs a different function.
The injector VIC has 2 choke coils even though the injector only has 1 connection which connects to the inner electrode, the outer electrode is grounded through the engine.
Tony, Don, and others have mentioned that the VIC resonance is between the positive choke and the cell, and that the negative choke has no effect on resonance. I mentioned in the first post that resonance is the self resonance of the coils, but I think the cell effects resonance because of the antiresonance phenemenon.

Stan explains them as performing different functions in the tech brief.
One thing I think is important here is the diode placement. It prevents the AC from the secondary from reaching the positive choke.
