A big difference is that if you go to a gas station you’ll have both (and possibly more). At least in Europe. So while you need to fill with the right fuel unless the pump is broken or the tanks are empty the fuel you need will be available.

In the US, if you roll up to a random charging station you may or may not find a plug matching your car’s port.

I think the common mistake they’re alluding to is Europe and north America having conflicting standards for colour-coding the pumps. So here green is unleaded and black is diesel, which can catch American tourists unaware. (Especially so with language barriers, “sans plomb” in French is not intuitively petrol/gas/benzo)

As someone who has gone on many EV road trips over the years, I've never had an issue of rolling into a random charging station and not having the right kind of plug. All I've had to do is avoid Tesla stations, all the other brands have worked with my car. And now that I got a Tesla DC adapter that I keep in my trunk, I can do fast charging at a decent chunk of the Tesla stations.

NACS should help change that eventually (hopefully on the sooner side of eventually), as it wins the marketplace and chargers get slowly updated.
