Example hidden service issue

[Mike Cardwell]

In the documentation it tells you to set up an example hidden service
pointing at google.com, eg:

HiddenServicePort 80 www.google.com:80

I've just started looking at hidden services so I'm not exactly sure how
they work yet, but if I'm correct, by setting that up and testing it
surely you'll be connecting to www.google.com on port 80 from the server
with your hidden service and doing a:

GET / HTTP/1.1
Host: youronionaddress

Wont that give google a map of Real IP -> Hidden service name?
