If you destroy an area and some people lose one particular function, while other people only lose small fragments of the function - which seems to be true of Broca's region - can the function really be said to be localised?
IIRC there are some areas that are localized almost in the sense of a circuit.
Hearing is an example, which needs to process sensory information much faster (and more direct) than ordinary pathways would, in order to be able to construct spatial representation from latency differences.
However, in the context of the article you might be referring only to intertelencephalic processing, in which case I'd love to read a paper which compares the directness of hearing vs other modalities.
