Note that whether or not it says "from concentrate", this process is still happening. If it wasn't, they wouldn't be able to screen out pesticides and bacterial agents, and wouldn't be able to keep each jug to the correct concentrations of its component chemicals (which each have very different molecular weights, and so would band in industrial mixers) and so forth.

If you mean that you prefer actual juice you get by juicing an orange yourself, then sure. But "fresh-squeezed" orange juice at the supermarket is just organic synthesis without a freezing step. (Which is an important-enough distinction; freezing fruit, or its juices, denatures a lot of the nutrients.)
