M4 Documentation:

This chain demonstrates a useful application of the Materialisation operator. It is applied after a few preparation steps, the output of the last of which is used by several further preparation steps. This means that this output will have to be read several times when the preparation process is executed. Hence it is materialised, to speed up reading data from it.
