from the above page:

For example, if a buyer chooses international shipping and you specified free shipping as your first domestic option, you don't pay any final value fees on shipping charges for that item.

Ah, wrong, well at least on our invoice. On a listing we have, it is Free Shipping for domestic address within the USA.  We charged the buyer for USPS Priority International and now eBay has helped itself to a portion of that charge. 8% of the shipping charge to be exact.
