We don't yet precisely what was the point of the experiment.
But it is very likely that it intended to study propagation of such
updates. Not propagating them is a protocol violation, so in order to
observe anything beyond propagation times, they would have to intend
to cause protocol violations, which is, in fact, awfully close to
session resets (thanks to the BGP protocol design).
