-The build change detection described in the previous example would not have worked had the Dockerfiles been placed in the same directory, e.g. `/` (root). In the next example, the Dockerfile path for both components is `/` (root). Any change will always match, or be a child of `/`, and Radix will therefore always build both components.
+If the Dockerfiles for the two components in the previous example are placed in the same directory, e.g. `/src`, then Radix will not be able to distinguish between them. Any change in `/src`, or any of its sub-folders, will always match both components. See example below:
