ZFS: zdev names don't match devices

No. This is a quirk of the way the 10.x installer/ZFS works. There are a
handful of different ways to identify a disk on FreeBSD besides the
device ID, including UUIDs and gpt labels and such. Device IDs will
change if you ever add/remove/reorder the physical drives, so the
installer uses the other methods to be safer. I don't know why it uses a
mix instead of doing the same thing for each drive though.

I think you're confused about what a vdev is. "vdev" is shorthand for
'virtual device'. Disks (or partitions, or files) are grouped into a
vdev, and the vdevs are then striped together to form your pool. A vdev
doesn't have a "name", just a type (ie; mirror/raid/etc). The block
devices that the vdevs are composed of are what can have names.
