Not for caching, but you might experience some HTTP issues as the
rewrites are not always fully transparent. It is best if the internal
servers firmly know their official names. There is several cases
where your internal servers may expose their internal name to the
clients.

Correct.

That if you are using a redirector to map domains to their backend
servers the mapping must be unique for each unique URL. This because
Squid caches on the URL after redirection.
Think about the situation where you have a internal server hosting
several domains, and I think the 1-1 requirement will be more clear
to you.
