No worries. He will have a good job coming here. If he starts at a Regional he will build up his total time and eventually PIC time.
I’m not sure about the EASA PIC time. I guess what you mean is the time he acted as PF. That would count as PICUS time ( under supervision). An easy way to figure out if you can log PIC time is to ask yourself- who is listed as PIC on the flight plan and who signs the tech log/acceptance sheet? If it’s not your name then you are not the PIC.
