I suspect it's more efficient. The Amazon video mentioned that they found randomizing bin locations to be more efficient than any grouping. That's not particularly surprising when one considers that many non-physical storage algorithms benefit from randomization, but it's kind of fascinating that the physical storage of goods is a chaotic mess apart from the database that maps products to bins.
