For me, friend, I would explain the above as:
1. one model explains the causality of how consciousness & mind-&-body are tainted/polluted by ignorance
2. the other model merely explains meta-physical causality.
In other words, using the language of the commentaries, one model is Dhamma-Niyama (pertaining to dukkha & its cessation) and the other model is merely Citta-Niyama (pertaining to how the mind generically operates).
Anyway, the above is merely my opinion on the subject.
For example, the quotes below from the same sutta show how the causal arising of consciousness is "neutral" (citta nikaya) while the arising of dukkha follows another causal principle (Dhamma Niyama).
Red colour = citta niyama
Blue colour = Dhamma Niyama
Dependent on the eye & forms there arises consciousness at the eye. The meeting of the three is contact. With contact as a requisite condition, there arises what is felt either as pleasure, pain, or neither pleasure nor pain. If, when touched by a feeling of pleasure, one relishes it, welcomes it, or remains fastened to it, then one's passion-obsession gets obsessed. If, when touched by a feeling of pain, one sorrows, grieves, & laments, beats one's breast, becomes distraught, then one's resistance-obsession gets obsessed. If, when touched by a feeling of neither pleasure nor pain, one does not discern, as it actually is present, the origination, passing away, allure, drawback, or escape from that feeling, then one's ignorance-obsession gets obsessed. That a person — without abandoning passion-obsession with regard to a feeling of pleasure, without abolishing resistance-obsession with regard to a feeling of pain, without uprooting ignorance-obsession with regard to a feeling of neither pleasure nor pain, without abandoning ignorance and giving rise to clear knowing — would put an end to suffering & stress in the here & now: such a thing isn't possible.
