Chaining transformations provides an extra degree of flexibility and power to performing transformations. For example, if two transformations have a common element; you might separate this element out into its own transformation, and then perform the original transformations from the common point. The separated transform could even produce a useful model itself.
You can chain transformations by selecting the 'Perform Transformations on result' checkbox in the 'Model Transformation' dialog, so that transformations that have already been performed on target Classes are executed automatically next time that Class is transformed to.
