I don't think it's scientifically or mathematically possible......In real life.
True! This shot went double distance, 190 to the hole and 190 away which means that it left the flag with the same impulse that it had at the clubface, while it's supposed to stop on the green and thus should have used up most of it's kinetic energy. There must be some weird energy transfer from the flagstick!
We had more reports like this five years ago and sometimes spoke of marble flagsticks then ;)
OTOH, there are considerable bounces from the flagsticks in real golf! Youtube shows quite a few unfortunate outcomes off the greens from the PGA Tour etc., sometimes into the water. At Merion, they have stiffer flagsticks due to the baskets, causing some trouble at the US Open.
