What you really need is the critical path mapped out rather than multiple tasks in parallel. People generally cook doing one thing at a time - prep this, chop this, add to pan, now chop this so on and so forth.
For a nervous cook I can see this being slightly confusing, or at least a non-optimal presentation of the information. For an experienced cook it's just noise.
I think you're onto something laying things out visually, I'm just not sure that this is the way it will work best.
