That looks quite different. According to the article, the key feature of the bullwhip effect is that it goes both too high and too low.

Exactly. It's a very different phenomenon from group velocity.

Both commonly happen after supply chain disruptions. Bullwhip effect happens over the entire chain, while group velocity happens on a single stage of it.
