It explains the temporal heating behavior at some scales. But it doesn't give a mechanism of heating. It could be electron beam target heating. But it could also be mediated by plasma waves.

The electron beams need acceleration and the most common suggestion is x-point magnetic reconnection providing up and down voltage gradients due to changing magnetic field. But the amount of electrons needed is unphysically large; the entire electron contents of the relevant volume of the corona.

There are plasma wave models that don't require unphysically large parameters.

These two (and a couple other) options aren't clarified by the observation of heating profiles. With the launch of Parker Solar Probe and the DKIST (diffraction limited solar telescope) the two models above will finally be testable. Spectroscopy of ion species by DKIST will tell what kind of heating is happening and Solar Probe will be there to measure the input from the corona.
