When a Region of the submachine StateMachine reaches the corresponding exit point, the submachine state is exited via this exit point. Source Unified Modeling Language 2.5.1
An exit point connection point reference as the source of a Transition implies that the source of the Transition is the exit point Pseudostate as defined in the submachine of the submachine State that has the exit point connection point defined. Source Unified Modeling Language 2.5.1
14.2.3.5 ConnectionPointReference ... a connection point reference represents a usage (as part of a submachine State) of an entry/exit point defined in the StateMachine referenced by the submachine State. Source Unified Modeling Language 2.5.1
a submachine Statemachine can be exited as a result of: reaching its FinalState; triggering of a group Transition originating from a submachine State, or; via any of its exit points. Source Unified Modeling Language 2.5.1
