In #20 there is an example which shows the output of this action used as the task-definition input of another use of this action. I ran into a different use case for this type of usage today as I have a task definition which contains multiple containers which need to get updated URIs before I can deploy and update my service. Thought it would be useful to document this for other users to find.
Made a small modification to the README which describes how to use this action when the task definition contains multiple containers in the containerDefs section.
