I think what they mean is something that would cause client to do something at the same time (could be all sorts, some synchronised crash, aligning timers to clock-time, etc.). If the requests aren't user-driven then yes, you likely would want to include some jitter in the first request too.

Funnily, you'll notice that some of the visualisations have the clients staggering their first request. It's exactly for this reason. I wanted the visualisations to be as deterministic as possible while still feeling somewhat realistic. This staggering was a bit of a compromise.

Not sure what is meant by "if your exponential backoff counter is not global", though. Would love to know more about that.
