The hosted domains feature of a web hosting account denotes the number of registered domains that you could add within the exact same account. Registering a domain address and hosting it are two totally different services although a lot of people consider them to be the very same thing. While the registration means that you become the owner of a certain domain address, the hosting aspect is what in fact enables you to have a web site because this is where your data and e-mails will be. As these are two different services, it is possible to register a new domain address with one company and host it with another one by modifying its name servers (DNS) - the domain is going to work in the exact same way just as if it was registered and hosted using the same company. It's also important to know that changing the hosting means directing the domain name to another company and not transferring it.
