Context

Currently, the child threads are displayed in a separate flow tab:

Proposition

A better user experience could be created by displaying the entirety of the thread within the primary diagram field.
The following is a simple and generic idea of how this concept could look, given the current example:

Considerations

While the example provided is composed of a few simple nodes, actually executing this idea within a complex workflow and thread environment is challenging. In fact, if the thread's flow is complicated enough, it may even be worth keeping the tab functionality to serve as a form of abstraction.

This would be a huge improvement. As you mention, it's really hard to figure out where each thread is waited for. And we'd also need to represent some form of hierarchy because that's how variables work with each other.

I'm not a UX guy, but I can help answer workflow-related questions.
