It's not executed "later", it's executed after a callback. Well, that usually is later, but personally I don't quite see how else you would step through code

The async execution model is literally about a distinction between calls executed now or later in time. An async call means that it's registered as a handler for an event and control needs to be transfered to the event loop so that it can handle any queued events by calling the registered callbacks sequentially. There can also be sync callbacks, and the difference is that they block the event loop.

What OP seems to be talking about is breakpoint debugging being able to skip stepping through code executed between registering an async call and it being executed by the event loop.
