That is correct. The record was encoded with the 4 channels so
no further processing was needed.
At WEZO (Rochester, NY - 101.3), we used to have a 4 channel
tape player which fed a Sony SQ encoder for an hour each
evening in 1975-76. Don't think anyone knew / cared / listened for it.
Dropped program after a year. No one complained.
At the time there were 3 different / competing systems.
SQ from Sony / CBS. Sansui's QS and another which I can't recall.
Consumers did not know which to support which helped to kill
the whole idea.
