三中，初明深防。不問有無，慮有別眾，過分倍集，故曰深防。實下，示限分。故下，引證。此明凡為比丘，隨處有界。則知《僧祇》七樹，不屬一人；證上半減，義無差矣。

In the third: first clarifying deep protection. Regardless of whether there are people or not, out of concern that there might be a separate assembly, doubling the assembly beyond one's share is therefore called deep protection. From "actually" onwards, indicating the delimitation. From "therefore" onwards, citing evidence: this clarifies that whenever one is a bhikṣu, wherever one is, there is a boundary; thus we know that the seven trees of the Mahāsāṃghika-vinaya do not belong to a single person; proving that half is subtracted above, the meaning is without error.
