That's correct. It's a label and nothing more.

It gets complicated trying to handle two LVMs on the same host if they
have the same volume name, so some distributions try to mitigate the
possibility by including a hostname in the volume name. (Why would you
have two LVMs with the same name? I wouldn't plan to, but it can come
about when swapping disk drives about.)
