My thoughts exactly. The quoted blurb could be easily taken out of context. They could have been describing how to get the maximum benefit, not the minimum, as in: you need to clear at least 13 feet to get the maximum area for motion detection. I mean, really, how could a camera detect you 15 feet away, but not 10 or 5 feet away. Besides the concept demos we've seen of it working clearly show it working at very close range.
