You are forgetting that the  two carburettors are mounted on a common 
intake manifold, so both carbs feed all 6 cylinders. I theory, and I 
think also in practice, you would be able to run the engine with only 
one carburettor. It will not run very well but still be running on all 
cylinders. As someone mentioned, the three carb model doesn't have this 
common intake.
