That's covered by the use of "expected" I think (as expected != is).
That said, trying to read it in English even if they struggle will benefit them more (even as developers, but also professionally) than using some regional translation as a clutch.
I wouldn't recommend the same for literature or news of course, but in programming english is like part of the basic science.
There's a lot of developers that don't speak English fluently. Of course they have a hard time, but that statement is false.
