Yatvādhikaraṇamenaṃ (yatvādhikaraṇametaṃ)

Dear Pāli friends,

I would like to make sense of the passage on guarding sense doors:

Idha bhikkhave, bhikkhu cakkhunā rūpaṃ disvā na nimitataggāhī hoti nānubyañjanaggāhī, yatvādhikaraṇamenaṃ cakkhundriyaṃ asaṃvutaṃ viharantaṃ abhijjhā domanassā pāpakā akusalā dhammā anvāssaveyyuṃ, tassa saṃvarāya paṭipajjati, rakkhati cakkhundriyaṃ, cakkhundriye saṃvaraṃ āpajjati.

Would you please explain whether yatvādhikaraṇamenaṃ (in some editions, yatvādhikaraṇametaṃ) applies to the following text, as in translation:

"And how, friend, does one guard the sense-doors? In this a monk seeing an object with the eye, does not seize hold of either its general appearance or its details. Because anyone dwelling with the eye-faculty uncontrolled could be overwhelmed by cupidity and dejection, evil and unwholesome states of mind, therefore he practices to control the eye-faculty, guards it and gains control over it. So one guards the sense-doors.

or to the preceding text, as in translation:

"And how does a monk guard the doors to his sense faculties? There is the case where a monk, on seeing a form with the eye, does not grasp at any theme or variations by which — if he were to dwell without restraint over the faculty of the eye — evil, unskillful qualities such as greed or distress might assail him. He practices with restraint. He guards the faculty of the eye. He achieves restraint with regard to the faculty of the eye.

In the Kaccayana's grammar it is written:

Caggahaṇena aññatthāpi pañcamīvibhatti hoti. Yatohaṃ bhagini ariyāya jātiyā jāto (M. ii, 306). Yato sarāmi attānaṃ (Khu. vi, 175), yato pattosmi viññutaṃ (Khu. vi, 175), yatvādhikaraṇamenaṃ cakkhundriyaṃ asaṃvutaṃ viharantaṃ abhijjhādomanassā pāpakā akusalā dhammā anvāsaveyyuṃ (D. i, 66; S. ii, 384).

By taking "ca", there is also the fifth inflection in other meanings. Sister, from the time I was born by a Noble birth. From the time I remember myself; from time I became knowledgeable; for that reason, evil unwholesome dhammas, covetousness and grief, torment (the bhikkhu) who dwells unrestrained in the eye faculty.

In the Niruttidīpanī there's a passage:

Imaṃ bhikkhuṃ vinayaṃ ajjhāpehi, atho enaṃ bhikkhuṃ dhammaṃ ajjhāpehi, ime bhikkhū vinayaṃ ajjhāpehi, atho ene bhikkhū dhammaṃ ajjhāpehi, etaṃ bhikkhuṃ vinayaṃ ajjhāpehiiccādinā vattabbaṃ. Tamenaṃ bhikkhave nirayapālā, yatvādhikaraṇamenaṃ bhikkhuṃ iccādīsupi anukathanameva.

which seems to indicate that yatvādhikaraṇamenaṃ applies to the preceding text?

Also, 'yato' is a clause with a shade of question, akin to 'which'. The same clause with a shade of answer, akin to 'because', would be 'tato'?
