  The nearly zero optical forward scattering and anti-dual conditions are
usually associated to the so-called second Kerker condition, at which the
electric and magnetic responses are phase-shifted by {\pi}. However, as we
show, this condition is insufficient to both give rise to the nearly zero
optical forward scattering and the anti-duality symmetry, in striking contrast
to the actual view of the problem. Interestingly, we demonstrate that near the
electric and magnetic dipolar resonances, the energy radiation pattern in the
far-field limit resembles to the one arising from the first Kerker condition,
with nearly-zero backscattering.
