What happens if there is a "Forward flow of brass" ?
Where does the 'brass' come from?

Brass fails for me when the neck wears out or splits.
I never have failures at the expansion web unless of course the FL die is set wrong or the chamber has excessive headspace.
AI chambers are a waste of time and money and hurt resale value.
You must be running pretty mild loads then? If you have to trim brass you'll eventually get a case head separation. The brass that your trimming has to come from somewhere and it can really only flow in one direction. Yes setting your FL die to only neck size and only bump the shoulder back will increase case life.
