I don't think reformatting would have helped in this scenario (in fact according to the blog post, he believes it made it work).

I don't own any macs, but I think this is some sort of "remote lock" function provided by apple.

It sounds like the buyer did not re-register the device with their own Apple ID (assuming that is possible).

This is correct. You are supposed to set up your own iCloud account on the device, to make sure that no one else (except maybe Apple) has remote control over the device.

Actually, I don't remember reading about that in the Apple security whitepaper. Does Apple claim that they can't remote-lock your device without your password?
