Interesting. With sides 1 and 3 on one disc and 2 and 4 on the other disc, you are describing the slide automatic sequence used on 78s before WWII in the so-called throwoff changers. I include a photo of one changing records.

After the top record of the stack played, the changer slid the top record off. Thus, it reverses the stack as it goes through it. (And sometimes it broke the record - worst changer I ever saw.)
With a drop changer, sides 1 and 4 are on one disc and sides 2 and 3 are on the other disc. This lets you just turn the entire stack over to play the rest of the album.
I have only two Microgroove albums labeled for slide automatic operation.
- One is a 45 album made like a 78 album made for slide operation in 1952.
- The other was the Rick Wakeman "Journey to the Center of the Earth", where the album is pressed for drop operations, but they put the wrong side numbers on the labels.
