It's not more air, it's some of the air. More air would require larger displacement, more rpm, or something along those lines. The side tracked air is used to pull up fuel from the enricher jet in addition to what is being pulled up through the idle circuit.

I forgot to answer that yes, the gas is pulled up into the enricher body and then with the air that pulled the fuel up goes into the carb throat via that big hole just in front of the throttle plate. It's the same air that was going to get there anyway but now it has a lot more gas in it.
