The strategy you've propose doesn't seem likely to me. It would take a lot of effort to steer them to the kite, only to have to chase them out again to repeat the process. I think it's far more likely that they herded/chased them toward the kite, and from far enough away to keep them from scattering, and jumping over the stone 'walls', and when the herd traversed the kite, it gradually bunched up as it got closer to the point of the kite. At the point would be the kill zone, with hunters waiting to slaughter as many as possible.
