I didn't think that was what he was saying. As I recall what he said was that he hadn't encountered a twin socket where (as he demonstrates) the 2 earth pins are isolated from one another. In reality therefore the "dual earth terminals" on this twin socket are single earth terminals, one for each socket.
No doubt I've misunderstood (and I'm certainly no expert) but I can't see how this socket could meet the high integrity earth systems requirement precisely because the 2 earth terminals on the socket are not connected together internally.
