Bizarre object 10 million times brighter than the sun defies physics, NASA says

The Eddington limit applies only to conventional fusion stars. In the case, a neutron star is sucking in more than a solar mass of material per year. It is expected to be brighter than a star could ever be at equilibrium.
 
Am I correct in understanding that the Eddington limit applies to the amount of energy released inside a star, mainly around its core, so that the release of the energy needs to be slow enough that it does not blast the star apart against its gravity, but this neutron star is apparently releasing this energy from its surface, so it does not push out from the star's center?

As I understand it, your explanation is correct. The outward pressure of the light and hot gasses is exactly balanced by gravity at the limit. A neutron star, or balck hole accretion disc is emitting light far above the limit, but then it is, in fact, blowing apart. So it too may be subject to the limit.
