But this does need to be the case. Sometimes a graphical notation is a great help. For example, many tensor computations in differential geometry become straightforward using Penrose's graphical notation. Is that the case here? It is difficult to say, as the authors fail to present that notation separately to the results.

Yes, it is the case here as well. Reducing terms can be tricky because of distributive laws. The graph-like representation makes reduction algorithmically easier.
