[CQ-Contest] CQWWDX Contest Out of call area operation

[Alan C. Zack]

I would like to throw out a question that is not clear in the rules
(at least not to me).
This situation pertains to domestic, CONUS 48 states call areas.  Ham
A lives in a call area with a large number of hams, therefore more
competition to him during the contest.  However, he has a vanity call
sign for a different call area in a different CQ Zone than where he is
physically located.  He enters the contest using his assigned call
(but the call does not match his actual location nor his actual CQ
Zone).  
Scores and awards are listed BY CALL AREAS.  In this situation who is
he competing against?  Is he competing against people in the call area
of his license even if he is in a different call area and CQ Zone? 
Seems as if he should be compelled to sign his call, portable as to
the number for the call area and zone he is actually transmitting
from.  Will the contest gurus list him according to the address used
on his log placing him in the call area where he was actually located
or will he be listed in the call area of his license?
