WebA latter paper figured out how to guarantee liveness in partially synchronous network (PBFT). So the accurate way to restate your two bullets: Yes, it does guarantee both liveness and safety as long as 2/3rd +1 are honest and there is a known maximum to the delays (aka the network is synchronous). The intuition on why asynchronous networks …
