You already have this property, because After is reversed during shutdown.

 From systemd.unit(5):
Note that when two units with an ordering dependency between them are 
shut down, the inverse of the start-up order is applied. i.e. if a unit 
is configured with After= on another unit, the former is stopped before 
the latter if both are shut down.

Those two lines are wrong. ExecStart is justed exec()ed, not through the 
shell. What happens here, is that the script gets three arguments 
"start", "|", "/usr/bin/logger". It likely ignores everything but $1, so 
it seems to work.

You might use StandardOutput= (see systemd.exec(5)), or just leave the 
redirection out entirely, it is now the default to redirect stdout to 
syslog.
