[GE users] Does a shadow master really improve reliability

I'm still concerned about the sentence from the Grid whitepaper I quoted: "The goal of installing a shadow master is to eliminate a single point of failure in the cluster, but adding a remote Berkeley server for spooling adds an additional single point of failure."

This implies that if the shadow master fails, then the Grid will fail. This is what "adds an additional single point of failure" means; correct?
Is it true that if the shadow master fails, it will cause Grid to fail?

Is there any documented way to install a shadow master such that Grid will not fail when shadow master fails?
