Just as photon that does least trajectory in space in beam, by being in middle therefore not doing the rotation on outer edge of bean is faster by taking less trajectory, but photon on outer edge takes more trajectory in same observers time, but age of photons may slightly differ. Therefore their speed can work in inverse for self observed.
