To be perfectly honest I think thats a bunch of crap. First off, a choke isnt to cut down air, its to increase vacuum at idle so that the damn car will run when cold and the engine needs more fuel.
The heat (much more important) and slight pressure differential will cause some of the fuel to vaporize, but the fuel doesnt instantly boil as soon as it flows into a the vacuum.
