Could you update the now obsolete documentation (perhaps just delete the no longer correct remark):
Documentation/vm/numa_memory_policy.txt:
MPOL_BIND: This mode specifies that memory must come from the set of nodes specified by the policy.
The memory policy APIs do not specify an order in which the nodes will be searched. However, unlike "local allocation", the Bind policy does not consider the distance between the nodes. Rather, allocations will fallback to the nodes specified by the policy in order of numeric node id. Like everything in Linux, this is subject to change.
