What -s option is for, in add-account & add-user CLIs,What is the usecase

This is What Usage info says,

-s SUFFIX, --suffix=SUFFIX
                        The suffix to use with the reseller prefix as the
                        storage account name (default: <randomly-generated-
                        uuid4>) Note: If the account already exists, this will
                        have no effect on existing service URLs. Those will
                        need to be updated with gswauth-set-account-service

I did the following:

# gswauth-prep -K gswauthkey
# gswauth-add-account test -s crap -K gswauthkey
# gswauth-add-user test admin testing -s crapadmin -K gswauthkey
# gswauth-add-user -a test admin testing -s crapadmin -K gswauthkey
# gswauth-add-user -r test re_admin testing -s crapreadmin -K gswauthkey
# gswauth-add-user test tester testing -s testerscrap -K gswauthkey
#gswauth-list --json test -K gswauthkey
{"services": {"storage": {"default": "local", "local": "http://127.0.0.1:8080/v1/AUTH_test"}}, "account_id": "AUTH_test", "users": [{"name": "admin"}, {"name": "re_admin"}, {"name": "tester"}]}

I am not able to see where suffix is placed.Or will be be used somewhere?
