Baffling.  I can't recreate this problem.

If you're interested in debugging further:

# cp /usr/lib/systemd/system/systemd-sysctl.service /etc/systemd/system/
# vi /etc/systemd/system/systemd-sysctl.service

replaced the ExecStart line with:
ExecStart=/bin/strace -f -e trace=file -o /var/tmp/sysctl.trace 

# reboot

/var/tmp/sysctl.trace should tell you whether or not the files are being 
opened.  Beyond that, my only guess would be that some other service is 
restoring the defaults, but I have no idea what might do that.
