That's because DFCO only works above 1100 rpm, or around there. Once you get below that rpm, it starts putting gas and spark back to the engine so it wouldn't stall. Obviously it would be a marketing horror to try and sell a car that stalls every time you take your foot off the gas. My Mazdaspeed 3 also has DFCO and I can never feel any difference when it goes on or off.
