It's for capacity, spectrum usage and SNR, smaller nodes have better SNR as there's less devices and taps on them to cause noise, having nodes physically segmented means that the same clean frequencies can be used rather than having to extensively stack, it reduces laser load as there's less RF hitting the node and 2 x 18Mbps for each node is twice the capacity of splitting 2 channels between them.
It makes perfect sense to do this, indeed VM have always done it. It was far from uncommon for ntl and Telewest to split a downstream across 2 or more nodes while having the 6 upstream ports split between them on an MC16 card.
EDIT: Just FYI upstream bonding works fine however it required new line cards on both 10k and BSR, the BSR requires the
RX48, the 10k needs the
MC20X20V or
MC3GX60V.
