Yes, it's only the source of the miles that matters.
If it were an international Y award, could both companions still get free EC if PNR were split?
No, you need to be on the same PNR.
What if EC was selected for free and then PNR split, would GM be booted from EC or forced to pay up?
The system would kick you out upon splitting the reservation or removing the Platinum FF number.
