Backfires come from unburnt fuel detonating in the hot exhaust manifold - heat+fuel+oxygen.

The opposite happens to Grafs explanation when you close the throttle; now your mixture is over rich, so either not all or none of the fuel is burnt in the cylinder and is dumped into the exhaust manifold, where it now encounters a lot more air (oxygen) and the heat radiated from the hot metal of the exhaust manifold.

Cold engine, what factor is missing… ?
