I think if I recall correctly the danger was with 2 separate processes of VFP on the same or different computers generating non-unique values when run in the same timeframe. This was the reason for concatenating the machine name plus maybe the process id. Auto-increment was easy and worked well, until my client wanted to bring a laptop offline and do real work with it. It turned out that the method I'd started with (sys(2015)) was the method I returned to, and upon reflection was the overall easiest, most reliable, and most flexible of the VFP-native pk-generating options.
