Most issuers report whatever the statement says. USBank, in particular, apparently reports the balance as of the first of the month. (Note that they can actually report on whatever date they want but most choose to report statement balance.)

Your score is high because your utilization is probably still relatively low. Your score probably went up at the beginning of your 9 cards because the extra available credit brought your utilization down enough to offset the new credit ding.

It's worth your time to compare what's on your credit report to your previous statements; that way we know of any anomalies.

EDIT: Just noticed you're not the OP. But the logic still applies: Adding a card or two will often help utilization more than hurt from new credit. Your credit is probably great because you still have low utilization even with balances reporting.
