The reason they do that is because Chrysler is the luxury line of cars that Dodge makes. Chrysler is supposed to compete with Lexus, Mercedes-Benz, BMW, Cadillac, Acura, Infinity, and so on. Dodge is out there for the middle class customer, that can't afford high class cars, or that doesn't want to pay that much for a car. But most automakers now days have a different name for their higher class cars. Toyota=Lexus, Nissan=Infinity, Honda=Acura, Ford=Lincolin. so the Chrysler version of that car will be fully loaded, with leather seats, and a better looking instrument panel, that may be wood grained instead of just vinyl, and maybe even a more powerful motor (but not always). But if you look past the exterior of the car, you will notice the higher quality of the Chrysler vehicle, when you compare it to the Dodge vehicle. The most noticable difference is between the Dodge Voyager Minivan, and the Chrysler Town and Country Minivan. Take a look at the two of them, and once you get inside them you will instantly notice the difference.
