There is more in the last step of kusala mula PS which adds more argument to my position.
The last step in 2.10.1.1. Mahākusalacitta says: “… bhavapaccayā jāti, jātipaccayā jarāmaraṇaṁ. Evametassa kevalassa dukkhakkhandhassa samudayo hoti”
But we know that jati of a Sotapanna (Anugami) is filled with more dukkha than just “jaramaranam“. Thus this is not the physical birth or the new bhava in the human realm. This can be just the registry in namaloka.
