Your definition of Sagas sounds right for me and I also would define them so.

The only change in your description I would made is that a saga is only a eventhandler (not a command) for event(s) and based on the receiving event and its internal state constructs a command and sents it to the CommandBus for execution.

Normally has a Saga only a single event to be started from (StartByEvent) and multiple events to transition (TransitionByEvent) to the next state and mutiple event to be ended by(EndByEvent).

On MSDN they defined Sagas as ProcessManager.
