As far as I understand, the UK gave Apple an order that has effective worldwide extent to insert a backdoor. Clearly you can't have a backdoor that only works for people in a certain location, since people are not fixed in one place. Apple chose to partially comply with the order, by disabling ADP for UK users, instead of inserting a backdoor. Apple is making the distinction here between UK and non-UK, so they can define a "UK user" however they want. A foreign citizen travelling in the UK almost certainly won't be affected. In other words, they aren't handling this case legally, or at least that is a matter that may be resolved in court if the UK is unsatisfied with Apple's method of compliance. Apple would seek to challenge the UK's jurisdiction in that case.
