Default 1930s carburetor question

So I've noticed something with older carburetors, specifically the Zenith on our A as well as whatever fancy carb is on this supercharged Duesy.

As heard in this video when the engine is revved and the carb is closed fast the engine stutters / misses.

Is this because the mixture leans out momentarily and if so why? What changed in more modern carbs to stop this?
