Update-config not updating all references to

I used the update-config scripts to change my host name after editing SITE_HOST in proxy.yml but noticed it's was not updated in all the nginx config files - each of these entries still used the old URL:

./sites-available/monolith_commcare_static:20:              oldurl.com;
./sites-available/monolith_commcare:55:              oldurl.com;
./sites-available/monolith_commcare:72:                    proxy_redirect http://oldurl.com https://oldurl.com;
./sites-available/monolith_commcare:81:                    proxy_redirect http://oldurl.com https://oldurl.com;
./sites-available/monolith_commcare:90:                    proxy_redirect http://oldurl.com https://oldurl.com;
./sites-available/monolith_commcare:126:                    proxy_redirect http://oldurl.com https://oldurl.com;

I performed a proxy deploy with

 commcare-cloud monolith ansible-playbook deploy_proxy.yml --skip-check

And it appeared to correctly update the files. Is this expected behavior?
