The purpose would be that if the dealer had a group of similar cards purchased at the same time he could look and see if others might have color added or were altered in some way. If I were a dealer I would want to know so I could sell with the best information to buyers ..... not just letting "the buyer beware".... also it may be educational for him ( if it actually does have color added) assuming he was not being deceptive in the first place. Finally, the dealer may know where he got the card (or cards) in the first place and then may consider that information in future purchases from that source. I think bringing the card in the holder and showing it to him rather than just telling him would be the right way. OR>>>>>> he might just tell you to shove it and then you would know more about that dealer for the future as well!!!
