Combining bands gives you 3 levels of assistance - one with the thicker band, one with the thinner band, and one with both bands. This allows you to do sets where you start with the thicker band and then add the thinner band to squeeze out a few additional reps. As your strength gradually increases, you can switch from double bands to the thicker band and then the thinner band alone.
