It might be the case - but at this point I'm not an expert. :) I have noticed that if you activate WOL and the execute ifdown on them some NICs "switch off" completely anyway and some stay active. I guess the reason is different driver implementation but I might be wrong.
You need a system that supplies enough power to the NIC while the PC is off (standby, really), for WOL to work. Some motherboards have jumpers for how standby power is handled (+VSB - positive Stand By, for keyboards, mice, other peripherals), and some have headers to to connect a power lead from the motherboard standby supply to a socket on the NIC.
