It's not all that seamless, but its not all that strange.

If the A/C gets warm the car will usually turn back on. In my friends 2.7 ecoboost F150 it will tell you on the onboard computer why the car didn't stop/start and I believe HVAC is one of the reasons, in addition to things like engine too cold, or engine too hot.
