Yes it does. Its a choice that a data publisher has to make i.e., handle 
mapping using the combination of virtual domains and re-write rules or 
by making mappings explicit using owl:sameAs relations.

I demonstrate in my personal data space, you can use http: and https: as 
mechanisms varying behavior of HTTP operations based on identity. For 
instance:

1. https requests provide a mechanism for using the WebID + TLS 
authentication protocol to verify a WebID that denotes an agent 
(end-user, their browser, or some other piece of software operating in 
"user agent" capacity) -- remember, this is just an extension of TLS 
which is already implemented by all existing browsers

2. http requests enables use of digest, openid, and oauth based 
authentication .

Thus, a fault on https: can be re-routed to http: and if the 
authentication with the net effect being a processing pipeline for 
identity authentication using a variety of existing authentication 
protocols. Once an agent's identity is determined, data access policies 
determine access to data associated with one or more named graphs  (or 
graph groups).

Drive mounted to my personal data space.
