It is indeed a bit unclear, perhaps it is better with the whole last paragraph
removed.

You can do the latter if you also use StrictSubnets = yes AND Forwarding kernel.

You can do that (without needing the above options). Packets are then sent to
only one of the two gateway nodes, unless it is not reachable, in which case
they will be sent to the other one. You can use Subnet weights to explicitly
give one of the nodes a higher priority than the other.
