It is basically two exposures onto the same piece of film, once for the image and once again for the sound (optical, DD, DTS, SDDS).
Was this ever used as a back up method for the sound elements at any point, Like the sound fx, music ect?
Sorry been traveling. Yeah you could use them as backup but older films general stored their tracks and stems on mags since mags have wider frequency response and fidelity then opticals. But that's only if the studio kept all the materials which is always a good question.
In fact that one of the great things about Dolby Stereo is not only the matrixed channels but the improved fidelity for optics.
And of course 70/80s it moved to digital.

It made an already expensive format even more so. Nowadays 70mm tends to use the digital audio formats.
To add to this the materials needed to create the mags are toxic and banned. That's why DTS developed their 70mm format. And even that is done for now since The Hateful Eight was the last DTS disc issued by Datasat. Sad days.
DTS assumed the 70mm blow-up program would continue but the addition of digital sound to 35mm (and the birth of multiplexes) killed the special 70m engagements.
