Most likely, TFL omitted to say "and if you have... issued outside the

I understand the need to launch the thing in stages, so buses first
makes a lot of sense, but I think that foreign card acceptance is one
thing that should have been sorted-out first. It is just asking for
trouble, argument and confusion in a great tourist destination.
