Sorry, but try these definitions form our friends at EASA.
‘Pilot-in-command’ means the pilot designated as being in command and charged
with the safe conduct of the flight. For the purpose of commercial air transport
operations, the ‘pilot-in-command’ shall be termed the ‘commander’
and...
"In accordance with 8.e of Annex IV to Regulation (EC) No 216/2008, one pilot amongst the
flight crew, qualified as pilot-in-command in accordance with Part-FCL, shall be designated
by the operator as pilot-in-command, or, for commercial air transport operations, as
commander."
Note the words "ONE pilot amongst the flight crew"....so only ONE P1. It therefore follows that only one person can log a flight as P1.
The wording "or, for commercial operations as commander", implies they are also referring to private flying.
Mark 1,I see you are in the USA where the rules about logging flights may be different.
