"if you main desk outputting DMX fails, the backup desk won't output DMX through the failed desk"
That is correct. An A/B switch would be good to have in this case. It really depends on what fails on the primary console. If the desktop process crashes and the internal DP process is still running then it is possible that DMX will still come out of the failed desks even after you switch over to the backup desk. This is not usually what happens in a failover case so having a quick way to switch the DMX lines over is a good idea.
