Even if fuel is cut, some is left in the head, gets pulled into the cylinder, is now lean and has the potential for det. Now, if any of you have ever had a bad coil pack, you will understand that when ignition is cut, even under high boost, the car just falls flat on it's face. So, by cutting spark progressively (one cylinder at a time) you can slowly and softly prevent over revving. As a side benefit, the fuel still being in the cylinders cools the combustion chamber further reducing the chance of det.
