I believe that communicating a plan already in motion is not the same as expressing an idea one might have. If I understood correctly this article points out to the latter. While having already a plan in motion, you will want to share it with the people and colleagues that you want in order to continue an idea. But if you have an idea that you want to set in motion, and just share it around with everyone there's a high chance that it wont kick off.
