This picture is incorrect; it shows three incoming photons, but only two outgoing electrons. There should be three outgoing electrons. This is the whole point of the photoelectric effect, and why Einstein got the Nobel prize for this: the correspondence between the number of photons and the number of electrons is 1-1.
I do not agree with the observation. The outgoing electrons are as a result of two photons which hit the metal earlier. The incoming photons are yet to strike the metal surface.
