Never Have to Sort Laundry Again (except that you still have to sort)

Color Catchers sound wonderful - you toss your new fabric into the wash, add a color catcher, and any excess dye jumps right onto the catcher, and not onto your other fabric.
So I bought some. They are available at the Schlecker drugstores here in Germany, about 2 Euro for 15 sheets. Here they're called Farbfänger, and this brand is called Farb Magnet, or color magnet.
Never having used them before, I carefully read the instructions. And did a double take.

The next to last sentence in the Wirkweise paragraph says, "You can skip sorting colors and whites." Sounds great! I can't wait to never sort laundry again.
On to the actual instructions.
Step 1: Sort the laundry just like normal.
Wait?!? What? I thought it just said I don't have to do that anymore!!! Arrgh.
OK, I didn't really believe I would never have to sort again, but this kind of BS is annoying.
