Long-range fork is possible if network participants are manipulated or forced to switch to another fork. In practice, the correct fork is communicated from entities who control the majority stake, such as exchanges. In the case of network disruptions, there might be multiple valid forks, and choosing the correct one is arbitrary, because there isn't one. There's no objective consensus similar to proof-of-work.
