Russ merely states the distance. I think you are making the mistake of thinking Russ is stupid. That would be a big mistake, I have worked with and for some very bright people indeed, and he isn't far behind any of them.
When I say that I don't know how Russ George thinks the synchronization is mixed up with quantumn entanglement I mean it. Entanglement is usually for systems which were once coincident in spacetime but are now separated. Does this mean that the pellets were once part of a single pellet? Does it mean that particles emanating from one pellet lodge themselves in the other, now distant, one? I don't know because I haven't come across anything so far in George's blogs that covers this.
