There’s no data being overwritten in the mechanism I described.

  I believe his point is that in encrypting the data, you are overwriting it - with the encrypted version, which without the key is effectively 'random data'. It's not actually random though, so I don't agree that the data has technically been deleted. Do agree with you that it might as well have been though, so certainly should be good enough.

    The idea is slightly different though: you encrypt the individuals data before it ever goes to permanent storage, backup or so. And when it’s time to delete that data, you discard the key instead, effectively making that data inaccessible.
