This implies to me that the engine is still getting fuel. Also, when you brake in-gear and you approach idle RPM, the fuel is restored to avoid stalling the engine.

I should have said "in the last 10 years or so", instead of grouping all FI cars together like that.
The only way I know to test it is to start engine braking at 2000+ RPM and use an instrument to check for fuel flow, like an injector pulse width identifier.
You could also use an AFR, I suppose, since you'd be going lean as hell with no fuel input.
Oddly, I'm still unsure whether my 4th gen Civics had this setup or not. I never tested for it, but I've seen claims that the older Hondas actually were designed with it.
