Note: the 7:30 corresponds to the first hour in
[Timer]
OnCalendar=*-*-* 07..23:30
RandomizedDelaySec=5m
Persistent=true
of the /etc/systemd/system/timers.target.wants/anacron.timer file.

This is indeed the case. The anacron(8) man page says:
After the command exits, Anacron records the date in a
special timestamp file for that job, so it can know when
to execute it again. Only the date is used for the time
calculations. The hour is not used.
So I got the issue on the first machine because I upgraded
between midnight and about 7:30.
