How is it possible to manage mulitple servers using Helm?

I have been e-mailing The Planet and as far as I can gather, they think that it is not possible!

They say "Helm will not allow you to manage multiple servers, each additional server would need its own instance of Helm to manage your customers on it."

Why then is there a section under Home > System Settings > Servers where you can add another server?

Do you have to have helm on each server and login to it on each seperate server to manage the customers on it rather than one account to manage them all, even if they are networked?
