Probably due to the <<“~site”>> in your pattern.
Administrators have a shortcut in all ACL checks, so that they can do anything
regardless of ACL modules.
So for administrators this code is never reached.
For normal users this code is reached and then the topic-words might not match
with the pattern.
Trace this observer if you want to see all patterns.
