I think the word "transferable" just adds a bit of wiggle room that  
allows the server not to send the representation even if it has one.  
An example might be a client that is not authorized to view the  
resource, and the server 303-redirects it to a preview of the  
resource. Another example might be a representation that is too large  
for a mobile client on a slow connection. There might be many reasons  
why a server, even though it technically speaking has a  
representation, would prefer to redirect a client to some other  
resource instead.

(I didn't write Roy's text and am obviously just guessing.)
