The rules are inconsistent to say the least
The 10 year span is merely a paperwork exercise. Having renewed my own UK CPL recently I was not required to take any further test. The privileges are inherent in the licence - no testing is required to keep the licence current.
Do you have any ANO/FCL references, as I can not find any documentation for the rules you suggest exist?
