Correct error in description of ZIP -> geo mapping

We do not set weights equal to 1 when a ZIP overlaps multiple
geographies; we set a geo weight (weight_in_location, in the new
pipeline) based on the overlap of that ZIP with those geographies, and
count the response in each of those geographies according to its weight.
