Just meant that the leading geometry can be very unsmooth (e.g. add
canceling weights
on every other key) and still have smooth frontweights.  Not really
suggesting
anyone would really do this.  Just an example to make the point that smooth
geometry (of everything, including leading pattern) is a good thing.
