To me, this proves very little about how independent development teams would perform with experienced engineers working with present day design tools. It's possible that the results would be the same, worse, or better, but I hope this isn't the most recent research that's been done on this.
The main issue with this approach is of course - cost. So the question is whether having two systems with uncorrelated fault paths is worth doubling the development expense.
