When ever you run a batch process it follows certain hierarchy of executing the scripts.
Here we maintain a job scheduler where all the job are scheduled in an order.
Where it shows each and every job has predecessor job to be executed before the ongoing script is executed.
So first, before executing the job it will check for the predecessor job and then start executing, so there is not point of collision of scripts.
Every job is executed sequentially.
