Recall that a branch table is a table of contents listing the pages in a lesson. When you insert a branch table into a lesson, you can also insert an end of branch later in the lesson. The pages between the branch table and end of branch become a branch. For example, a lesson with two branches might look like this:

Cluster 1 
Question Page 
Question Page 
Question Page 
End of Cluster 
Cluster 2 
Question Page 
Question Page 
Question Page 
End of Cluster 

For a Jump, if you select Unseen question with a branch, the student will be taken to a question page that they have not yet answered correctly in this session. That question page will be in the same cluster as the current page.
