Not quite.  The diagram is a prop to help the audience understand how
iterative modeling works in almost any context, including the design of
software unrelated to modeling or simulation.

It's just like any visual aid to any presentation.  Can it really be
that hard to understand?  It's just like any of the bazillion cartoons
we see all over the place.  E.g.:
