How does the token-classification pipeline handle entities that span over several tokens?

The entities with the same label are merged into one entity.1
There is a label for the beginning of an entity and a label for the continuation of an entity.2
In a given word, as long as the first token has the label of the entity, the whole word is considered labeled with that entity.3
When a token has the label of a given entity, any other following token with the same label is considered part of the same entity, unless it's labeled as the start of a new entity.4
