That's because the CBP officer who evaluates your request for entry on a permanent resident visa has the discretion to say that you are "likely" residing elsewhere and "remind"/"advise" you of the requirement to be permanently resident inside the United States in order to keep PR status. The six month rule is less of a rule and more of a presumption but if a CBP officer sees a series of entry stamps all hovering around that six month mark, the officer can make that note and the next officer might declare that you've abandoned PR status and you'd then have to go through the process overcome that.
