frankly, it's because it's not a great analogy, because it requires you to know a fair bit about not-from-concentrate orange juice.

To transport NFC juice, they have to take out all of the essential oils, etc. that will spoil in transport. Meaning, if you drank orange juice from the tanker truck, it wouldn't taste like much. Once it gets to wherever it's being bottled, they add all those essences, oils, etc back.

With me so far?

The cool/interesting thing about this, and sort of the thing that makes the analogy, is that these companies will modify what oils and essences they put back in to suit the tastes of that geographic area. Maybe Northern US cities prefer a sweeter orange juice, where in western Canada they prefer a more tangy orange juice. They can modify their mix to suit.

Interestingly, this came up in the news again just a few days ago and I didn't even know until i went looking for sources.

So the analogy makes sense, but only if you know about this one specific thing about NFC orange juice. That makes it probably a bad analogy.
