The problem with that is that the person's intent isn't to cross the language barrier.
Many languages have idioms involving body parts like this. In French it's couter les yeux de la tete, similar in Italian where it's costare un occhio della testa. One in Mandarin that means something different is 削足适履, about cutting your feet to fit your shoes.
I get that idioms don't always translate well (some actually do, especially literal ones that are less referential like cost an arm and a leg) but I'd be careful before invoking misunderstanding with theoretical groups of non-english speakers.
And yet, all of those could be misinterpreted by someone who is not familiar with that.

If you're being cautious (as is common for a large website to do) then this is totally backwards -- you would actually need to be careful with invoking understanding when it comes to theoretical groups of non-english speakers. You can't start by assuming that everything that is said is going to be understood perfectly (Though I really wish that was possible, it would make it a lot easier to teach math, physics, history, etc).
