I think the relative URLs are key. The relation between the WebID Profile Document and the WebID
is made clearest by the notation such as either

 <#me> a foaf:Person .

But the problem with this is that for servers that have different URLs for each of 
the representations, this way of writing things means that the WebID for <card.n3>, 
<card.ttl>, <card.rdf>, <card.jsonld> will end up being respectively
<card.n3#me>, <card.ttl#me>, <card.rdf#me> and <card.jsonld#me>

it is better then to write in each of the representations 

 <card#me> a foaf:Person .
where <card> is the content negotiated document.

I can see that a NTriples version of the same file could be helpful. But the 
origin of the resource needs to be carefully marked.

In any case I think we should explain the above problem, as it is one people
will make quite easily and unconsciously.

I think adding an @prefix would be better for that, or a statement of where the
document was served from exactly.

Having an NTriples version of the file may help for beginners.

That's up to the editor. Not a big deal.
