The way I read it is something much simpler than attacking the
encryption - it seams to be about operational procedures security.
Think if somebody mis-configures something on the first layer you
still have the second layer. Now if you add two separate teams
managing each layer then you have a

Not mis-information. You could easily end up enabling a
meet-in-the-middle attack just like double DES.
