ISCSI: Login request/response Statusn/expstatsn clarification..

["Ranganathan, Deva" <Deva_Ranganathan@adaptec.com>]

Julian, all,
I am looking at the latest draft draft-ietf-ips-iSCSI-10.txt  and also the
earlier 0.8 and 0.9 draft.  
Under login request, expStatSN is described in draft 10 page 66 - Section
1.12.10 as 
" ExpStatSN This is ExpStatSN for the old connection. This field is valid
only if the Login request restarts a connection (i.e., X bit is 1 and TSID
is not zero). "
However for login response, StatSN is described in page 70, Section 1.13.4
as

"StatSN For the first Login Response (the response to the first Login
Request), this is the starting status Sequence Num- ber for the connection.
The next response of any kind, including the next login response, if any, in
the same login phase, will carry this number + 1. This field is valid only
if the Status Class is 0. "
Am I missing something?
-Thanks
Deva
