Think of it this way...with both axles of the truck on the scale, now you grab the tongue of the trailer pick it up, you're now holding up 680#, pull it over to the truck and set the tongue onto the ball with the trailer tires off the scale. The weight of the truck has only increased by the same 680#. I think you're confused with the changes that loading can have on axle weights.I'm not sure that's the correct (most accurate) way to do it. From physics, we know that using a lever changes the amount of force needed to move an object. Your ball hitch is "X" number of feet behind the rear axle. Essentially, from the rear axle to the ball is a lever. This means you were really measuring the extra amount of pounds added to the rear axle. In the end, your tongue weight would be less - possibly quite a bit. And while it may trailer fine in a straight line, you could run into a very dangerous situation if you had to suddenly swerve. I had originally thought your picture showed the axles too far forward, but the number you posted sounded dead on. But with this info, I would move the axles. Or, at the very least, double check the weight the proper way, first.
