Just curious, do you know of any system where that recommendation was
not followed? On all motherboards where I have seen a AMD-8131 or a
AMD-8132, they were alone on their hypertransport link, and other
"northbridges" (more precisely hypertransport to pci-express or
pci-whatever, often nvidia) with a "MMCONFIG BAR" where on one of the
other available hypertransport links in the system.

Here is the PCI configuration of the HP DL585G2.
You can see two nVidia CK804 PCIE root ports at bus 0 and bus 0x40.
Each of them has an 8132 connected as a subordinate bridge.
