BPMN uses the term ‘merge’ to refer to a point in the process where two or more alternative sequence flow paths are combined into one sequence flow path. Source
It is exclusive merge, so once an execution arraives at gateway from any of incoming flows, process continues past the gateway.
In the above model, we have a parallel split with no symmetric parallel join so two executions can arraive at the exclusive merge at different times and since it is exclusive merge, then process continues past the gateway as an execution arraives at it so we ending up having two tokens following this gateway.
An interrupting conditional boundary event is attached to “Task 2” so when the condition “jobCompleted == true” is satisfied then the task is canceled “if it is active”.
If the user decides not to continue and the automated work is not completed yet then execution will stay at conditional intermediate catch event until work is completed.
