I agree, it needs to be on whenever pax are on board!
I once had a captain tell me that he doesn't run both because he doesn't want to "over-pressurize the duct work."

That was amusing! Some of the gate A/C's work really well and some don't. That's one of the first things I check when I step on an airplane.
