Im sorry to say that but what you had cited is incorrect
I know a couple of engineers who own a uk issued license b2 / b1 and they know a jack squat about thier job, and i ( im just a trainee without even a license yet ) know much more than them and they've been working for years on the aircraft .
It has nothing to do with wether the license has been issued in france or the uk , it all relies on the person himself, if he likes his job or not, if he gets to grips with it or not.
