It’s not that every word you say will be memorable, it’s that a random sampling of what you say will be remembered by different people and you cannot control (well cannot is a perhaps to strong of a word, but saying you can control it is probably wrong) when and for whom it is memorable. You build a thick layer of good memories with a person, that random sampling will be better, but it’s always possible some random bad memory will stick in someone’s mind, and that’s true no matter how careful you are. But being careful can help. So... In a way the OP is right, but I think they push the point too far.
