Yes, there is a reason for it.
If Round Robin is used 50% is served on another server.

It's just in case when siteA has very great problems (like a broken fiber,
or a fire in the server-park)
In normal situation the traffic must no go to siteB (both sites have another
stuctur).

We hope we never have to use it.
