User role change

I have a question. Our site is changing a user role from one role to another automatically after one year. I want to use this plugin to remove the users after 30 days if they do not renew their membership. Will this still work correctly with the user roles changing. They get changed to a “subscriber” after one year of membership and I’d like this to delete all “subscribers” after 30 days, but I’m not sure if it’ll still work or if it only applies to the role the user is when the user account is created. Please let me know.
