This consciousness turns back; it doesn't go further than name-and-form

In SN 12.65 , we read about the cyclic relationship between consciousness and name-and-form, which has been asked in this question . However, this sutta also has the curious phrase in bold below. What does this phrase mean? "*This consciousness turns back; it does not go further than name-and-form.*" How does it fit with the rest of sutta? As translated by Bhikkhu Bodhi: > “Then, bhikkhus, it occurred to me: ‘When what exists does birth come > to be?… existence?… clinging?… craving?… feeling?… contact?… the six > sense bases?… name-and-form? By what is name-and-form conditioned?’ > Then, bhikkhus, through careful attention, there took place in me a > breakthrough by wisdom: ‘When there is consciousness, name-and-form > comes to be; name-and-form has consciousness as its condition.’ > > “Then, bhikkhus, it occurred to me: ‘When what exists does > consciousness come to be? By what is consciousness conditioned? ’ > Then, bhikkhus, through careful attention, there took place in me a > breakthrough by wisdom: ‘When there is name-and-form, consciousness > comes to be; consciousness has name-and-form as its condition.’ > > “Then, bhikkhus, it occurred to me: ‘**This consciousness turns back; it > does not go further than name-and-form.** It is to this extent that one > may be born and age and die, pass away and be reborn, that is, when > there is consciousness with name-and-form as its condition, and > name-and-form with consciousness as its condition. With name-and-form > as condition, the six sense bases; with the six sense bases as > condition, contact…. Such is the origin of this whole mass of > suffering.’ As translated by Bhikkhu Sujato with Pali version included (from here ): > This consciousness turns back from name-and-form, and doesn’t go > beyond that. > > *paccudāvattati kho idaṃ viññāṇaṃ nāmarūpamhā na paraṃ gacchati.*
