Yes, it disabled MSI only on devices under that bridge. But if it's the northbridge, that would be everything, no? But I don't know what devices those PCI_VENDOR_ID_AMD, 0x9602, PCI_VENDOR_ID_ASUSTEK, 0x9602, things are. If they are just a PCIE->PCI bridge rather than the root bridge, then everything looks fine to me.
