No, sounds like there wasn't any "supply disruption", rather a "demand excess" from people who thought there might be one. Those are different things.
Bill Gates could cause a potato shortage if he started buying up all the potatoes in America. But that wouldn't be a supply disruption if farmers are still growing potatoes at the usual rate.
We can argue about the exact definition of the word "supply", but the bottom line is that when the suppliers are no longer capable of providing goods to stores, it's kind of pedantic to say "it's not a supply disruption!".
Okay but if Bill Gates says "there's gonna be a potato shortage!" and then causes it by buying up all the potatoes, it's a bit backwards to say "wow that Bill Gates is so smart, however did he predict the future potato shortage while those stupid poor people couldn't?"
