I took basic reinforced concrete too. I agree on the function, but being the intellectual prisoner of building codes that I am, I would detail it right even if I was working for the contractor. Believe it or not I had to refinance my truck to pay income taxes from my home business last year and cutting corners on government contracts violates my sensibilities.

What I learned from basic reinforced concrete design is that the function of the ties is to prevent the buckling of the vertical reinforcement. Now if the vertical reinforcement is not required for strength, in what instances then that the vertical reinforcement will buckle? Since the horizontal shear or trust will not be transferred to this pedestal, then you don't even need to strengthen the pedestal to resist shear. In my opinion, you don't need intermediate ties. The minimum ties are sufficient. The pedestal is basically an extension of your footing since it is not subjected to large compression loads.
