This seamed rather cumbersome and inflexible. I found that one can achieve the same effect in a more intuitive manner in the video sequence editor (VSE) by using multiple scene tracks with different camera overrides set. You can then use soft cuts in the tracks to open holes in the higher tacks to achieve cuts to and from lower track cameras. This makes for a much more visual and intuitive editing system as you can see what camera is in action at each frame etc.
On the flexibility front one can use hard cuts to create time jumps, repeats or other effects.
