I get that. With this quote, I see how it could be construed. Don't mean to think for Chad, but this one could conceivably be taken more than one way.
I'm not saying the swing will teach you to clean, jump, or snatch, but just simply that the hip extension of KB swings could create some muscle memory that might make learning or developing other movements easier and faster.
I remember a Strength Coach Podcast with Jonathan Chaimberg (sp?), the strength coach to GSP and other top MMA fighters noting that he wasn't a huge fan of KBs, but that they did teach double extension well. Swings aren't much for teaching extension at the ankles, but they are beneficial for teaching the extension of the hip and knee.
In the end though, you're better off teaching someone how to jump before they touch a barbell or a KB. And, if you have to teach someone how to jump, they're f'ed and aren't notable athletes anyway.
