It becomes somewhat clear after senior leadership changes: after a few months you will hear others use words that were previously only used by the new incoming leader.Although this isn't always a good thing.
After a UK company I worked for was taken over by a US company, we started to get these nauseating "all hands" propaganda calls, hosted by the senior executives. The rank and file staff were indeed later using words previously used only by the incoming leader: they were the butt of just about every office joke for weeks, and demonstrated the raw contempt that the people doing the real work had for the empty rhetoric the executives delighted in making us all sit through.
Maybe it was some 4D chess thing intended to boost morale after the takeover. Yes, I'm sure that was it. :-)
