俱舍論疏 24.19

24.19

論「此或名曰至總集斷故」，釋異名也。雖超越者先斷二，後斷三，次第者先斷三，後斷二，兩種不同。至得果時，俱集五下分結盡無，為一味得故，故二種不還皆得名為五下分結斷。

The commentary states: "This is also called … because of the collective severance," which explains its alternative names. Although the leaping practitioner previously severs two and later severs three, while the gradual practitioner previously severs three and later severs two—the two kinds being different—when they reach the attainment of the fruit, both collectively exhaust and eliminate the five lower fetters into a single taste of attainment; therefore, both kinds of non-returners may be designated as having severed the five lower fetters.
