'man systemd.unit' says:
If one unit with an ordering dependency on another unit is shut down 
while the latter is started up, the shut down is ordered before the 
start-up regardless whether the ordering dependency is actually of type 
After= or Before=.

Based on the above rule, check all the ordering dependencies the unit has:
systemctl show -p After -p Before plymouth-reboot.service
