They advertise the jobs as ESL, but technically it's EFL. ESL applies to situations such as Mexicans studying English in America. It boils down to what most of the people around you are speaking, iirc.
So any SE Asian in their own country (except maybe in Singapore) is probably studying EFL.
It's usually advertised as ESL simply because the schools placing the ad don't have a clue, and misuse has led to an incorrect merging of the terms.
Does it really matter? It's still teaching English, isn't it? Same skills, same techniques etc.
