Unfortunately you didn't have any engine monitoring equipment running, so the following is mere speculation, but if there was e.g. a 'ping' which put a pit into the piston creating a hot spot in the previous cycle, then the 'pong' in the next cycle could have been prevented.

That is assuming the reaction isn't already going. If the cylinder wall is just about overheated then simply killing ignition won't reset the whole motor. The piston will keep moving (friction) and could be enough to push the cylinder wall over the edge.
Just some food for thought.
