That sounds correct. The 12v feed from the truck charges the battery. If (god forbid) the trailer breaks free from the towing vehicle, the breakaway switch is pulled, putting 12v from the battery onto the brakes, locking them up completely. Then your trailer is simply a large object hurtling down the highway uncontrolled, rather than a large object rolling down the highway uncontrolled on wheels.
