One can see the dynamics like this: the star is tidally disrupted and produces energy discharge via frictional heating (basically). Then the remnant gas is sufficiently spread out so as not to radiate much, then the dynamics of the accretion disk concentrate the infalling matter enough to heat up again and some of the material is ejected.
Given our simultaneous understanding of GR and other physical phenomena this seems like the most likely explanation.
