Bang the Drum Differently?

Here is another snare drum pattern of wear showing the joint, two-dimensional pattern of drumstick or brush hits on the head of the drum. Again we can see the central dark and quite circular contour of the region of most wear. This is surrounded by a more irregular discoloring of the drum head, likely from the metal brushes we see here. This is very different from the nearly circular pattern of snare drum wear we have seen earlier. Is this the results of different drummers and their particular style or of similar style drummers playing different types of music? Or perhaps both?
