The Michel Thomas Method in a nutshell

This video indicates that small mnemonic hooks are inserted for some words in the Michel Thomas method. This was not immediately apparent or seen in the 1997 BBC documentary about his method and wasn't immediately apparent in Harold Goodman's discussion.

Is it apparent in Goodman's session with his nephews? Was it part of Thomas' method originally or was it added later? Is it truly necessary or does it work without it as in the SSiW method which doesn't use it.

It will take some deeper dives, but ostensibly this method seems to look like that of Pimsleur, Mormon Church, SSiW, and other methods.
