Yeah, for sure, thanks for pointing that out. For them it seems like fluency is defined as the ability to work comfortably in a professional setting in that target language. I self studied some of their French courses and found them helpful. I've never taken a course of theirs before, but a family member did do a year immersion in Arabic as part of their training for the foreign service, and of course it was a lot more intense than self-study.
