In practice the subsystem vendor IDs are quite arbitrary and definitely not the same for all PCI devices per mainboard
They aren't even allowed to be the same for all devices on a mainboard: the subsystem IDs should uniquely identify the device, without having to look at the "regular" IDs as well.
I suppose. The device in this case is the MOTHERBOARD.
