Unfortunately the statement in LASORS has been misinterpreted. It is intended for people who have commenced a PPL in for example Cyprus, and then have been moved by their employer back to the UK, prohibiting them from completing it. It is not intended as a route of convenience; so if you do half the course in Brazil you will be told to go back and finish it as you live there.
Quite simply you need to do your licence in one country or the other, not half and half. As long as you have an ICAO licence you can then use it in the UK.
