I suspect that these examples were based on the VF5xx parts instead of the VF6xx because when these examples were created, the VF6xx parts may not have been available yet. The dates on the example PEx-Generated code is Feb 27, 2013.
I imported those examples into my Workspace in DS-5 (Ubuntu), but I am not able to build it - those examples are targeted for the IAR tool chain on Windows. However, I used them as examples to build my own PEx project. They were useful because they allowed me to see how the parameters of the components are configured etc.
