So, and forgive me for going off on a slight tangent, could someone explain under JAA rules flying in Europe with a JAA PPL and with another pilot with the same qualifications, what does one correctly log ?
The pilot who is in command of the flight logs the time as P1. Nobody else logs anything for that flight. There can only be one pilot in command. That's assuming neither pilot is a qualified instructor giving instruction.
The exception is an aircraft whos certification requires a multi pilot crew, but it's extremely unlikley that a PPL will be flying one of those.
