The scripts dropped there are executed very late during the shutdown
process at a time where all processes have already been killed and all
mount points have been unmounted or at least remounted
read-only. Touching a file in /var is hence simply not possible.

it's really executed right before the reboot() system call is issued.

See the docs, specifically, systemd-shutdown(8).
