    Does anybody can explain how the electron is able to emit and absorb the same (virtual) photon?

    It absorbs a photon because the electron is raised to a higher energy state by the energy from the photon.

    When the electron falls back to its default state, the energy will be released as a photon (with the same energy as the original photon).
    You can do everything right, strictly according to procedure, on the ocean and it'll still kill you, but if you're a good navigator at least you'll know where you were when you died.
