You're absolutely correct. The venturi tubes atomize fuel as it's drawn into the air stream under vacuum. This device deals only with the stream from the accelerator pump, which is introduced into the air stream under pressure. That's such a small percentage of the fuel burned in a carburetor, and as Davepl says, it's going to be vaporized except when the engine/intake are cold.
