Yes you are right that you could interpret it as being a mere location, however there are courts that cover all of the UK , e.g. the Supreme Court of the United Kingdom ( http://en.wikipedia.org/wiki/Supreme_Court_of_the_United_Kin... ). Likewise, a german court would have no juristicion over the rest of the EU (say).
If it was a german court decision it would be misleading to say "it was a EU ruling from a EU court which has no jurisdiction in any other countries/supranational bodies.", since that implies the court could have power over the whole of the EU. Likewise "UK court" might imply juristiction over all of UK.
