Manual trans & vacuum secondaries

I keep reading in various places that if you granny shift a manual transmission, i.e., let off of the throttle for each gear change, that a vacuum secondaries carburetor won't reopen the secondaries fast enough when you slam the throttle back to the floor.

Is there any truth to this?
