Oh, not even close. I speak Romanian, English, and French. For all of the others I looked up Google translations of the phrase "I think he joined a cult" - in all of them, the translation replaced "cult" with some equivalent of "sect".

Also, I noticed that for more obscure languages (including Romanian), it didn't, so that confirmed to me it's not some fully hardocded conversion - for languages where it has enough examples it understands the "proper" translation, for those where it doesn't it does the simpler thing.
