Funny, my testsystems come up with the log already rotated:
1 [1/3507]mh at emptybuster84:~ $ ls -lart /run/log/journal/*/
total 1,0M
drwxr-sr-x  3 root systemd-journal   60 Feb  3 09:23 ../
drwxr-s---+ 2 root systemd-journal   80 Feb  3 09:23 ./
-rw-r-----+ 1 root systemd-journal 512K Feb  3 09:23
system\@df0e6fdb74704597bc1caa52e21c2e51-0000000000000001-00059da7a4f87ae4.journal
-rw-r-----+ 1 root systemd-journal 512K Feb  3 09:26 system.journal
and the X bit already set.

But here is the proof:
1 [1/1534]mh at roll:~ $ ls -al /run/log/journal/*
total 5,0M
drwxr-s---+ 2 root systemd-journal   60 Feb  3 08:48 ./
drwxr-sr-x  3 root systemd-journal   60 Feb  3 08:48 ../
-rw-r-----+ 1 root systemd-journal 5,0M Feb  3 09:27 system.journal

This is a not-so-current sid (I have held updating for some days because
I didn't want the change to persistent logs affect the debugging) with
systemd 244-3.

Greetings
