Exactly right. The blower can continue to run, for a time, but the compressor cannot. For a short duration (e.g. at a stoplight), the air in the system may remain cold enough to remain in tolerance so as not to trip the thermostat and require the compressor, but (like all stop/start systems) I would expect it to restart if you're sitting very long. Thanks for putting the time into this response!Based off what I can see there is simply no way for the compressor to continue running with the engine off.
