Forest-Stage Discipline and Austerity
कस्माद्धि मैथुन श्राद्धे दातुर्भोक्तुश्च वर्जितम् । किमर्थ च त्रय: पिण्डा: प्रविभक्ता: पृथक् पृथक्

毗湿摩说道：“为何在施行施罗陀（śrāddha）之日，献祭者与受食的婆罗门都被禁止行房？又为何要将三份饭团供（piṇḍa）逐一分开、分别分配而献？”

Educational Q&A
The verse frames a dharma-inquiry: śrāddha is treated as a solemn, purity-centered ancestral rite, so the text asks for the rationale behind prohibiting maithuna for both host and officiating/feeding Brahmin, and for the doctrinal meaning of offering three distinct piṇḍas.
Bhishma, in his instructional discourse on dharma and rites, raises a specific question about śrāddha procedure—seeking reasons for (1) the ban on sexual activity on the śrāddha day for the performer and the Brahmin who eats, and (2) the practice of giving three separate piṇḍa offerings.
