In Bohr model Helium, the two electrons are moving on the same orbital But this model could not explain the experimental value of the Helium ground state energy correctly When the orbital planes of the two electrons are perpendicular to each other the two orbitals are proved to be just one de Broglie's wave length by the computatinal methods Please see the link below.
