I’m honestly not sure how Ford did this, but I’ve done it 2 or 3 times over the 5 years I owned and tracked the car with the same result. The engine never once over revved.

But the exact same behavior more than once is not chance. It’s design. Too bad BMW can’t do that. Perhaps the inertia of a 5L V8 was enough with fuel cut and spark retardation. Perhaps there was more to it. I don’t know. But it’s possible to do.
Makes you wonder whether the traction/stability control is braking the rear wheels to prevent the over-rev. It's possible, I suppose.
