Thats for a shared license, which means you have to pay for it.
From what I understand they use a trial reset system thats centralized.
But at the same time the script also gives root to the supplier, so be careful with this.
I personally have used these types of licenses in the past and they do work as long as you renew them, but you cannot contact cpanel directly or the other companies.
Its not nulled either.
But it would be interesting to see someone debug the code to see what else the binary does to the system.
