I'm being sarcastic that it is "clear", and being genuine when I say that orange juice industry lawyers argue that consumers are not confused about what "Not From Concentrate" means despite such contortions.

I do highly recommend Hamilton's Squeezed book for a more detailed expose. It's available from libraries, both physical and online. It's not for everyone, but if you care a lot about food regulation and the way that producers get around the law to deceive consumers, it's great.
