If I understand your statement correctly, then that's exactly why you should add the conflicts keyword. The only purpose of the conflicts keyword is to indicate that ports install the same files and therefore cannot be active at the same time. The presence of the conflicts keyword allows MacPorts to check for this earlier, before files have been downloaded and/or compiled, and provide a nice error message to the user.
