TASKTYPE_BREAK

In the mannual about TASKTYPE_BREAK, it says:
var2
This parameter specifies whether or not the TaskExecuter should check to receive task sequences from an upstream Dispatcher. By default (0), the TaskExecuter will see if it has any task sequences in its queue. If the queue is empty, or if all of the task sequences in its queue are task sequences that have already been start and broken out of, then it will open its input ports and receive a task sequence from an upstream dispatcher. However, if var2 is not zero, then the TaskExecuter will not receive anything from an upstream dispatcher before calling its break logic.

I cannot unstand this, will someone make it more clear? An example is preferred.
thanks

1. By default (0), the TaskExecuter will see if it has any task sequences in its queue. If the queue is empty, then it will open its input ports and receive a task sequence from an upstream dispatcher.

Does this mean the TE will wait until receive another TS, then go to break logic?
If the queue is not empty, what will happen?
