Teroc,
AFT's modular course in SA is JAA aproved by the CAA. Therefore, eventhough you are not in the UK, you are still deemed to be training under the authority of the CAA. So there's no problem in doing your PPL, IMC, Night, Multi, hour building in a JAA approved flight school in SA as long as you sit your CPL test and ATPL exams under the supervision of the JAA State that has approved the SA flight school!!!
Hope this helps.
