Yes, that is normal. SIP has difficulty separating the remote party 
identification from the authentication identification (although it can 
be done).

In CVS HEAD, soon _all_ SIP entries will be type=peer, because it's more 
logical this way.

I believe it can already be configured to work that way, if you disable 
access to "guest" connections (I've not tried it, though). Remember also 
that it works this way because there are number of providers out there 
(Broadvoice being one) that will _not_ authenticate when they send you a 
call, only when they register.
