Running commandline with -h overwrites endpoint

As it says, -h option is overwrite the host name in the all endpoints, i.e., host name will be part of the endpoint. That option will help to run the same soapui project against different environments like dev, qa, staging etc. without open the soapui project and modifying.

Here, do you mean to say, it is overwriting the entire endpoing url with just hostname instead just replacing it for only hostname?
