This is true. The Mercury team referred to all the 2-mic experimental recordings as "binaural" to 
separate them as a class from "stereo" 3-channel recordings. Because thrre-track tapes were lost in 
a handful of cases, the "binaural" edited master was what was used for the CD. If I remember 
correctly it's fewer than 5 cases, maybe only 1 or 2. (There are other cases where the 2-track tape 
recorded from the live 3-2 mix when the LP was cut was used, again because the 3-track master was 
lost, only a handful of those cases too).

I think, in the early stereo days, only Emory Cook consistently recorded true "binaural" tapes, in 
other words those designed to be listened to through headphones only.
