If we have 50cc exhaust gases in 500cc cylinder, the intake air is 450cc.
This 450cc of air is seen be VAF - and gets fuel.
Exhaust gas has ideally no oxigen and doesn't need fuel.

:D
At the exhaust valve, there is already A-F-mixture not air,
if some of the mixture goes to the exhaust, the AFR won't change.

Main problem with flowmeter, i see is, that these intake-systems must be
absolutely leak-free,
or un-metered air will enter and lean the mixture.
