[OpenID] is it true?

Yes,

The OP receives the cannonicalID from the XRDS as the  
openid.claimed_id and the LocalID as the openid.identity.  The user  
input is not passed.

This also happens with URL identifiers and delegation if there are  
http redirects involved.

I have argued in the past that the two fields we have in openID 2.0  
are problematic for identifiers other than URL and even for them not  
always sufficient.

Don't quite know where you are going with this,  but it is a known  
issue.
