Was the orbit of the orbiting space craft that much different to this Luna space station?

Very different.

The Apollo program used a lunar orbit rendezvous to land a vehicle on the Moon and return the astronauts to Earth, with the lunar orbit at an altitude of about 116 km above the Moon's surface. TheIn contrast, the orbit discussed in the referenced article is not about the Moon. The subject of the referenced article is the proposed Lunar Orbiting Platform - Gateway (LOP-G). This platform is currently planned to be placed in what is called a near-rectilinear halo orbit.

This near-rectilinear halo orbit (NRHO) is neither about the Moon nor about the Earth. It is instead a member of one of several families of pseudo orbits about the Earth-Moon L1 or L2 point in the restricted three body problem. Each of these families of pseudo orbits require the presence of both the Earth and the Moon. The delta V cost from a NRHO to the lunar surface is significantly higher than was the delta V cost from the low lunar orbit to the lunar surface used by the Apollo problem.
