Why the triggered transactions are not queued on the terminal?

If trigger transactions are defined for transient data queues at a trigger level and once the number of records written in the transient data queues reaches the trigger level, the trigger transaction will be invoked automatically by the TXSeries runtime. If the trigger transaction(task) is associated with a terminal, then the trigger tasks will be queued to run on the terminal as one task can be run on the terminal at a time.
