Can you please give some context here? /var/log/syslog is entirely rsyslog's domain, systemd has nothing to do with it. Maybe you don't have rsyslog installed? (which is perfectly plausible and doable, as you can enable the persistent journal). Is rsyslog.service running? /var/log/syslog is certainly getting logs on a standard vivid/wily/xenial system.
