Agreed, this is once again an outstanding documentary by MaineSail.
I had this same question when reading the article. Presumably, if the standard kits slips a pulley over the crank pulley, this is a common issue.
Its the part of the article that says fitting a new pulley over the water pulley would change the flow characteristics that might want a tweak. It seems the new crank pulley is already doing that, so you would think you would want a different dimensioned water pump pulley to compensate.
