Problem

The segment $O A$ is given. From the end of the segment $A$ there are 5 segments $A B_{1}, A B_{2}, A B_{3}, A B_{4}, A B_{5}$ . From each point $B_{i}$ there can be five more new segments or not a single new segment, etc. Can the number of free ends of the constructed segments be 1001? By the free end of a segment we mean a point belonging to only one segment (except point $O$ ).
