Bill Garlick used to handle this question.  It's true but when tuning ET, the 
difference is very small, enough to be negligible when tuning aurally.  When 
tuning an unequal temperament, it can and does make a lot of difference 
depending on what kind of temperament is used.  For that reason, temperament 
"correction figures" are always listed with "A" being at 0.0.  Some people 
who tune HT's don't like this idea however, and continue to use a "C" fork or 
start with "C" at 0.0 and use a pitch offset to get the general pitch to be 
as close to standard as possible.
