As a side note to this, I find it interesting that it's {bIyIntaHvIS bIchul ’e’ Da’aghta’}, rather than {bIchul ’e’ Da’aghta’ bIyIntaHvIS}, a thing which shows that the {'e'} of a sao can refer to something preceding the sentence which it has as an object.

It doesn't show that. The 'e' refers to the immediately preceding sentence, bIyIntaHvIS bIchul. 'e' doesn't just refer only to independent clauses, but to entire sentences.
