Shampoos and detergents have soaps that will leave a film if not rinsed. Even if the film is not visibly evident, leaving detergent on the surface will "eat" through your wax/sealant and be reactivated when wet by rain. Rinseless washes do not contain chemicals that need to be rinsed clean. Rinseless washes contain Polymers that encapsulate the dirt, lift it from the paint, and provide lubrication to the paint so it doesn't get scratched when you wipe it.

Even if I do plan on using the traditional 2-bucket wash method with normal car soap, if the car is really dirty (caked on dirt/mud/salt is visible) I will pre-rinse the car with a Rinseless wash, let it sit for 5 minutes, then use the pressure washer. Then wash it like normal.
