No not like that, you can think about it as a fork with an unknown number of transitions, like you have a fork and this fork say contain 2 steps and i want an N number of parallel execution for this path inside this fork to be executed, so i want to contain these 2 steps in some sort of a container than i can execute the same path N times, and this N times should be executed in a parallel manner.
I used the sub process so i can control how many times i can start this sub process as if it was a separate process and start this execution path as many times as i like and then all these execution will be handled by a join after the process state node.
