There's another, earlier, paper that you might find interesting "Simulating flocks on the wing: the fuzzy approach. doi:10.1016/j.jtbi.2004.10.003" with videos available at: http://itzsimpl.info/projects/ilb_synflocks.htm Thanx for a nice reference.

What this means is even with a flock size of a handful, there is no guarantee that they will, within a given amount of time, fall into a stable state of constant velocity. I find this similar to systems in physics which become chaotic once they exceed three components, the n-body problem being a famous example. And yet the result shows that the chaos should eventually die away. This also brings to mind the behavior of certain cellular automata, where a long period of chaos finally settles into a regular pattern.
