Cloning from mapped domain

Hey guys quick question about your cloner plugin. I'm just confirming that if I were to clone a mapped subdomain to create a brand new subdomain this won't create any issues?

I ran a test and it seemed that the mapped domain didn't get pulled over to the newly cloned subdomain, but I wasn't sure if there were any other potential issues with that?

In other words is it better to clone from a subdomain rather than a mapped subdomain, or does it make no difference?
