difference between subscribe(store) and dispatch?

For this effect,

@Effect()
triggerOtherAction$: Observable<Action> = this.actions$
  .ofType(SOME_ACTION)
  .do(() => console.log("This line works for both"))
  .map(() => new OtherAction())

When I dispatch an action, I can think these two ways

first,

Observable.of(new SomeAction()).subscribe(this.store);

second,

this.store.dispatch(new SomeAction());

what is the difference between above two lines? For the first one, it doesn't trigger other action, but execute the line of do() and reducer works well.

There is no reason to dispatch actions using code like this:

Observable.of(new SomeAction()).subscribe(this.store);

In fact, there is a good reason not to: the observable to which the store is subscribing will complete and that will see the store complete, too.

In version 2.2.1 of @ngrx/store, that's not a problem - as its implementation of complete does nothing - but with the current master, complete is implemented and dispatching an action as above will see the store complete and no further actions will be dispatched.
