I (chrisf) have been moving about on four different terminals.
I was at 192.168.10.23 two days ago and since then it hasn't been
used. I've been on and off 192.168.10.22 4 or 5 times today. I was
also on 192.168.10.20 this afternoon (as chrisf) but then logged in
later as user3.

Next, I login at the terminal with ip 192.168.10.20 as user1

Now I login at 192.168.10.20 and chrisf

So it seems that the update of ip's are correct but expired sessions
are reported leading to confusion.

I don't understand this. What's the difference between smb://$(echo
$NXUSERIP)/fd and smb://$NXUSERIP/fd ? Why do you use Exec[$e] (my
bash knowledge needs improvement) ?

What's the reason behind the added complexity?
