In our company, it is required for nearly everyone to do that. Since everyone is multitasking, the first time a point is made, that is to interrupt people from their other tasks, the second time is a place holder to prevent anyone else from talking while you stall for time, the third time is wasted because everyone is formulating what they were going to say in response (even though they still have not listened to what you want to say), then the final time your point is made while people are listening (at least the ones who were not interrupted by another task).
My girlfriends father does the same thing!!! Every time he has something to say, he repeats it over and over again, not using different words or anything - literally the same sentences.. That's still better off than when he asks me for directions or some other form of help.. He just does not let go.... I think he has trust issues :) In any case the sad part is that i cant tell him anything cause i need his need his approval to marry his daughter.. (i wonder how many times he will repeat his sentences then!!!!)
