Singlethread、Multithread、Synchronous、Asynchronous组合逻辑求证

All the diagrams and explanations I've found on this topic don't align with each other—there's no consistency at all. I've created my own diagram to map out how I understand these concepts fit together, and I'd be grateful if someone could help me confirm whether it's correct. The diagram uses a left-to-right timeline to represent execution flow.
