The name "default" is misleading. It suggests "the BE that boots
by default" or "the latest running state", but in practice it is
just the residue of the initial installation, with no NR flag. The
name and its actual purpose are mismatched.
To understand 'default' name choose you will have to move back in time
to 2012 when I implemented *beadm(8)* for FreeBSD:
- https://forums.freebsd.org/threads/howto-freebsd-zfs-madness.31662/
The *pool/ROOT/default *was back then (and probably is still now) used
by default on Solaris/Illumos - so I just recreated that - along with
*beadm(8) *tool - its parameters and messages.
Of course it can be changed - right now I use something like that
personally:

I still feel like my understanding of BEs is a bit weak and am still
learning but is seems there are common misconceptions shared around
about them.
I tried to explain /ZFS Boot Environments/ multiple times ... but I
still am not sure if I succeeded:
