My focus cuts the injectors as DFCO, but does not shut the throttle
Interesting, I haven't driven a DBW petrol engine (with a genuine throttle) to try this out - George is an old fashioned Fly By Pants throttle and is the first Petrol I've driven since 2002.

The TDIs would just shut off fuel because the demanded fuel was below the fuel needed for the engine to maintain its current speed - i.e. (for the ECU) it was on overrun.
