Let us suppose we have a ticket "abc" which is set using the set-ticket method. And that ticket "abc" is being reffered in 10 different flows. Then the control should jump to which flow out of the 10 or ideally what should happen in this scenario?
So, if all 10 flows are in the same case, you would hit all 10 tickets. This one to many relationship is useful if you have multiple flows/assignments that need to be updated all at once. The classic case is canceling a piece of work, you may want to send notifications to all the various stakeholders so they know why it's being canceled.
