THat's right but I don't regard it a difference since it just a normal
routine to swap it back with a L<>R fix on the summing master.

Actually they can't! I was a defining that the the phase reversing
channel has to be a little lower in level. That is to avoid a total
"hole in the middle" effect. But matching it all is up to the user to
do by ear and to fit the musical situation.

Alan Blumlein originally I would guess, although he was working with
microphones and got kicked into it by cinema theater sound. I first
heard about this routing from a studio engineer, then I tried it out
of curiosity and found it useful in some situations.
