Unique International Shipping/Billing Address Issue

A customer in Australia with an Australian billing address is trying to purchase gifts to be shipped to the US. After unchecking the “same as billing” box to indicate the billing/shipping addresses are unique and entering the shipping address, he is sent to the checkout page to enter his credit card number. The checkout page autofills with the shipping address info, not the billing address info and when typing in over the autofilled info, an error is returned that the billing name does not match the card details.

Has anyone seen this before? Is it possible this is a Mijireh or authorize.net issue?
