I don't think it's as well known as you make out, few people I have mentioned it to had no idea. I only found out by pure chance...
Neither the CAA or BALPA for those who still subscribe have made it clear to the expats who hold a current UK license, which considering how much you pay to keep your license valid and up to date is disgraceful.
Good luck with your case, I am sure that they are many in the same boat.
