The hosted domains feature of a hosting account denotes the number of registered domain names that you can include in the very same account. Registering a domain address and hosting it are 2 different services even though many people consider them to be the very same thing. While the registration ensures that you become the owner of a specific domain address, the hosting element is what actually allows you to have a website as this is where your data and e-mails are going to be. As these are 2 separate services, it is possible to register a new domain with one company and host it with another one by changing its name servers (DNS) - the domain will work in the exact same way as if it was registered and hosted with the same company. Additionally, it is extremely important to know that changing the hosting means directing the domain address to a different company and not transferring it.
