"Maybe the exhaust pressure reduces on throttle lift enough to allow the over-boost to pressurize the manifold."

If that was the case than the anti-lag process is defeted.

The whole idea of this type of anti-lag system is to is to burn fuel in the exhaust headers to make pressure that spins up the turbo during deceleration and idle.

The exhaust pressure in the exhaust headers to make all that boost during deceleration is going to be way higher than 930 turbo intake boost pressure will ever be so how will you ever get it in there?.

You're burning the air fuel mixture in the exhaust headers instead of the combustion chambers during deceleration and idle with this type of system.

Totally crazy idea on a street car.
If you read on you'll find they did this on certain disposable turbocharged race cars to try and still be competitive with the increasingly small air intake restrictors mandated by the FIA.
