The first paragraph of Section 5 seems to address the case of 401 and 
any other errors:

"For each conditional request, a server must evaluate the request 
preconditions after it has successfully performed its normal request 
checks (i.e., just before it would perform the action associated with 
the request method). Preconditions are ignored if the server determines 
that an error or redirect response applies before they are evaluated. 
Otherwise, the evaluation depends on both the method semantics and the 
choice of conditional."

The second sentence in Section 3 references Section 5 as far as when 
preconditions are applied.  This seems sufficient to me, but perhaps 
that is because I have read the document several times and know what it 
says in its entirety.
