How the Reseller Registration URL works?

How the Reseller Registration URL works on ASTPP Community V6

My configuration:

I created a reseller, during the registration process, the system created a Registration URL of the form “https://mycompany.com/signup/b2V1dmpwcHBJOXc”, however, when accessing this URL and registering a new customer from it, The user account is created under the control of the admin user and not under the control of the reseller, as would be expected.

Thanks for your help
