As I understand them, if you accept Euros at all then you also have to accept them from customers in countries outside the Euro zone such as the UK. So if you try to discriminate against Brits by charging more in GBP than in EUR, they can bypass it by exchanging the money themselves.
I assumed (and understood from the link) that it applies to all EU member states, which presently includes the UK. Since the exchange rate fluctuates, there must be some margin of error allowed, otherwise it's almost impossible (and certainly more expensive) to implement with more than one currency.
