rudestuff - your right. the FAA CPL was unnecessary in this case, but I understand it was originally part of an 'integrated' program that required the EASA & FAA CPL with the intention of actually staying on, getting the instructor ratings (EASA & FAA) and then instructing for 1000hrs which ultimately proved unnecessary due to him landing the airline job with really low hours!
Goes to show that if you take the FAA CPL out of the equation, it would have been even less expensive.
