Note about completions seems unclear in bind()

bind doesn't propagate completions from the source stream - the shared subscription is closed as soon as there are no subscribers to that Observable.

I'm having trouble seeing how these statements relate.

When an Observable completes on a shareLatest, all the observers are notified, they all unsubscribe, and the state gets reset for the next observer to subscribe.

When using bind this behaviour changes: it doesn't propagate the completion of the source stream, so all the existing observables will keep an active subscription to the shared stream. This leaves a question open: "what happens if another observer then subscribes on it?" and the answer is "it will not resubscribe to the source, it will just receive the latest value that was emitted".

Then "When will it reset its state so that it resubscribes to the source?" -> "as soon as there are no subscribers to the Observable".

I agree we need to rephrase this one better.
