The hosted domains feature of a website hosting account refers to the number of registered domain names which you could include in the very same account. Registering a domain and hosting it are two different services although some people consider them to be the exact same thing. While the registration signifies that you become the owner of a specific domain, the hosting element is what actually permits you to have a web site because this is where your data and e-mails will be. As these are 2 independent services, you are able to register a new domain name with one company and host it with another by modifying its name servers (DNS) - the domain address shall work in the exact same way as if it was registered and hosted with the exact same company. It's also important to know that changing the hosting means pointing the domain to an alternative company and not transferring it.
