In arXiv:1108.5413v1, Lee and Lee use several comparisons to argue that the physics of the three-band model found (Phys. Rev. Lett. 106 036401 (2011)) can be explained in the one-band model's framework (Phys. Rev. Lett. 91 057001 (2003)). While superficial similarities exist between the two sets of results, for reasons discussed in this reply, we disagree that they describe the same physics.
