Because that dash camera was a pile of you know what.
If there is some sort of science I'm missing here, let me know.

the danger is that the wire gauge chart is a matrix to keep the heat under control, meaning certain gauge wire and pass certain amount of current at certain distance.
with, say 14 guage wire, you can pass 8.5 amp at 200 ft, or 11 amp at 50 ft.
so if you charger support 48 amp. it already take consideration of the length of the wire. ADD extension cord to that requires your to redo the calculation and reduce max current accordingly, which those switch are not smart enough to do by themselves. but if you are aware of this, you can reduce the changing current and would be fine.
anyways... J1772 is essentially dead in the U.S. buying anything not NACS at this stage is just wasting money.

You would be surprised if you ever open one and check for your self.
the only thing charger controls is open or close using a relay, maybe with a fuse, if that's what you meant by controlling current. the entire AC charging and power control is with the car.
some tesla charger do talk to each other, and if you set it up correctly, they can signal to the car that two charger is sharing one 40A circuit, and the CAR then reduce the charging speed.
