For example, let's say table B is mapped from table A, and table C is mapped from table B.
A->B
B->C
The data lineage of C would show that C was built from both A and B. The impact analysis of A would show that it impacts both B and C.
With minor inner dependancies, this sort of thing is easy to do by hand, but when many, many dependancies exist, an autmated solution becomes more appealing.
