There can be two main reasons:

1. Their EVOO can reach temps ~200°C

2. They use medium temperatures on the frying pan (so they keep it at 180-200°C, or lower). This is especially true when you use pans with anti-stick coating, which literally break at high temperatures (it's even written in the instructions to avoid using the highest temperatures).

Yeah, for something like lightly frying some mushrooms, or caramelising onions (though butter is imo tastier for the latter) there's no reason not to use EVOO other than that it still won't be the cheapest option, but cooking won't get rid of all of its health benefits nor taste. I suppose maybe there's a case (I don't know if this has been studied or just people with differing anecdotes?) for cheaper than EV olive oil being as good as EV when using it for cooking over a certain temperature? I don't know.
