No.  This is a fine tuning of the effect the airflow
plate's deflection has on system fuel pressure, and
thus delivered fuel quantity.  A decent analogy would
be on an alpha-n EFI system, where calibrating the
throttle position sensor has a similar effect on
delivered fueling vs. air ingestion.

I believe this is only true for the downdraft fuel
meters; the updraft ones would not cause an air leak,
and would only allow a small amount of unfiltered air
into the intake system.  Here's an image of an updraft
unit, but almost everything is the same as in the
downdraft unit.
