Does Feynman say that? If an electron absorbs a photon, why would it create another one of the same frequency, and with polarization perfectly rotated by 90°?

Because of the layout of the electron orbitals.
Feynman certainly didn’t say anything like that, or only the photons with certain frequencies would reflect, those corresponding to the energy differences between various orbitals.
