Question Two Macintosh HD backups in one APFS Container

I have recently upgraded from Mojave to Big Sur. I erased and partitioned an external HD to have one container with 7 volumes. 5 of the volumes are SD backups of various data disks, but 2 of them are backups of MacintoshHD. In both the Startup Disk preference pane and when I do an option boot, only one of the two MacintoshHD backups appear.

In the Shirt Pocket best practices it says "format the backup drive as APFS, and use APFS's very flexible "volumes" as your backup destinations, one per source volume". I guess I have two volumes for a single source. Is that the reason only one of them boots?

Can I fix this problem by creating a 2nd container (on the same external HD) and putting the 2nd backup there?
