-     * TODO clarify why this is done
+     * This may not be required anymore. The goal was the following. Consider two subsequent task
+     * instances which are detected to be repeating tasks on a level defined by the
+     * preparationTaskHandlingStrategy. Then the replacement of these iterated tasks by iteration
+     * instances would result in an iteration instance with two children, both of them having a
+     * different task assigned which does not match the child of the iteration model. This needs
+     * to be harmonized afterwards.
+     * </p>
+     * <p>
+     * <b>But, because we introduced the harmonization of event tasks directly at the beginning and
+     * afterwards, we compare only based on object identity, this may not be required anymore.</b>
