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
Any guards associated with these entry point Transitions must evaluate to true in order for the specification to be well formed. Source Unified Modeling Language 2.5.1
An entry point is equivalent to a junction Pseudostate (fork in cases where the composite State is orthogonal): Entering via an entry point implies that the entry Behavior of the composite state is executed, followed by the Transition from the entry ... Source Unified Modeling Language 2.5.1
A submachine StateMachine can be entered via its default (initial) Pseudostate or via any of its entry points (i.e., it may imply entering a non-orthogonal or an orthogonal composite State with Regions). Entering via the initial Pseudostate ... Source Unified Modeling Language 2.5.1
