For people who wrap their own coils?

That's exactly what it means. It's an awkward way to put it in English, but its the sensible way to say it in several other languages (especially if an inanimate entity like a coil can't have a "self" in their grammar). Functionally bilingual people - folks who can operate all day, every day in a second language they've learned - often can't see any problems with direct translations like that.
