WCF endpoint address, default still available after specifying an address

These are my endpoints

endpoint name="rest" address="" binding="webHttpBinding" behaviorConfiguration="poxBehavior" contract="IActionService"

endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"

which makes the service available at /here

when I change the address to [say] 'rest'

endpoint name="rest" address="rest" binding="webHttpBinding" behaviorConfiguration="poxBehavior" contract="IActionService"endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"

the service is then available at /rest/here.

which makes sense, but it is also available from the original address of /here

I thought that the original address would not exist as I have set the address to 'rest'.

What am I doing wrong or misunderstanding?

Cheers
