The Auction houses are well aware of what grade a card would receive from a 3rd party grader. I say this because the houses themselves are some of the largest, if not the largest, clients to 3rd party graders. With that kind of volume, you certainly realize the grades you will receive.
Personally, I believe the auction houses overgrade raw cards, period. Stating that the auction houses have different grading standards than the 3rd party graders is probably not that accurate based on my feelings. There may be some slight nuances they may disagree with, as many on this board, (pin holes vs. downgrade, writing on blank backs vs. down grade, amount of paper loss vs. down grade etc.).
