For reversion to work, pressure in the cylinder needs to be less than in the exhaust manifold. Obviously the engine doesn't run under that condition through the whole rev range. It's done with fancy cam phasing.

I'm lost because earlier you were discussing scavenging and then switched to reversion. I think reversion works by setting the exhaust timing really late so both intake and exhaust valves are open at the beginning of the intake stroke.
Oh, well. We agree that it doesn't really play in this failure.
