No, it means the exact opposite. If you configure two default routes
Linux will randomly multiplex outgoing connections over the two routes.
As opposed to the case of a single route it will not even *try* to do
dead gateway detection on these routes anymore. Yes, I do think that
behaviour is silly. However, I haven't thought of a better way to do
it yet.

Doei, Arthur.
