The Santana's are headscratchers, given how good the earlier efforts were.
Normally vocals done in SQ mixes were placed centre front so no cancellation problem.
There was a way to encode four channels at once, by fudging the phase a bit. Latter test records such as the one included with the Space and Image Composer includes a test signal that they refer to as Center Top.
