If I understand it correctly, they would first slow one deck, and then slow
the other one. This process was repeated over and over, for as long as they
needed the flanging effect. If they needed to perfectly synch the sound, or
eliminate the flanging effect, it would always be simple to fade down the
volume of one of the decks, leaving only one of them audible.

Yes, this does sound difficult, but I believe this was how it was done
before purpose-built "flangers" were invented.
