I've setup a test VM with a split /usr.
While I can't quite reproduce the problem you have, I found this in the
logs (those are exactly the early lines that are missing from yours
unfortunately)

Apparently systemd considers the /dev/sda5 device as inactive so tries
to stop usr.mount, which might result in /usr being unmounted.

I guess that's the root cause also for your problem.
I think I have enough information for now to further investigate this on
my own.
