I've seen sockets with two earth points, but electrically they have all
been connected.

I thought so, thank you.

In the video (or maybe the comments) I think there is a suggestion that
if the two earth terminals on the crappy socket were used in an "in and
out" fashion (incoming earth connected to one terminal, outgoing to the
other) there would be no earth continuity with a plastic back box. Even
with a metal one, the earth continuity would be iffy.
