Implicit in your pdf example is that the return on capital (4%) is real rate of return.
Ie, what you are targeting is to have your portfolio earn a nominal return of of around 7% (= 4% real return + 3% inflation), if you are assuming inflation moving forward is 3%. If not, the npv of your portfolio will erode as time passes.
if you assume 5% inflation, then you are basically saying your portfolio needs to earn nominal return of 9%.
I think you now realize that 4% nominal return is not sufficient... need to take riskier investments.
To have a depreciating assets as time passes is harder to example, but would be easier to visualize using a excel spreadsheet. It is similar to calculating mortgage payment of each month and where the payment goes to: reducing outstanding balance or interest payment.

he just doing the 4% spending rule in reverse... instead of savings * 4% = spending... he doing savings = spending / 4%
