How do come to that conclusion? The representation returned upon GET depends
on a variety of factors, including HTTP request headers, time of day and so
on... So clearly a resource can have many representations.

Depends on how you define identity of URIs. For particular URI schemes, two
URIs may identify the same resource even if they aren't lexically identical.
