Why are there two LVM2 partitions?

That is not a usual setup.

Some history. Installed fedora server on the nvme. Boot partition and single lvm partition. Ran out of space in the lvm partition. Created a partition from the free space on the nvme and used pvcreate to designate it as a physical volume. Appended it to the original lvm for a single contiguous space.

from another installation that sees the drive

:~# pvs

Normally you have 1 LVM partition and then create LV's inside it.

This is an example of what I'd expect a normal setup to be.
