If the bags were screened for an inbound U.S. flight then it is likely they will keep chain of security custody and just xfer the bags to the connection.
Every single person that comes in from a foreign flight has to go through customs. When you go through customs if you have a checked bag you have to get the checked bag. They will not forward the bag for you. It will come out on a bag wheel in terminal. Remember the terminal is completely different from the concourses where you literally board a plane.
