Based on my own research, this is correct. For instance, if you charge $20k on a $60k card, it will not include the balance on that card in your "total revolving balances" used in calculating your FICO. This is slick, in that, if you have a card over $60k with a great BT offer you can take advantage of it without affecting your score. I have only tested this with one credit card, but the balance was definitely not included.
