I thought so too. Even if they’re all mechanical, it usually makes sense to keep the fan running across the evaporator to prevent moisture buildup (which will then sit in a place susceptible to freezing). It can also be more efficient to push this residual cold into the vessel.
My car’s AC gets funky if I don’t remember to turn off the AC a few minutes before shutting down.
I think there is a drain near the condenser to prevent this, if your car smells nasty after turning off your A/C you may want to make sure that’s not clogged. Also, if equipped on your car replace the cabin air filter.
