The reason Porsche's are known for it is as follows: With the engine in the rear, traditional Porsches typically run much wider rear tires than front tires (to a greater degree than in mid or front-engined performance cars.) This has a number of advantages, including being better suited to hard braking up to the start of (and even into) the corner, as well as massive corner exit grip under power. However, with lots of rear grip available, and even more available under power, it's easy to get into a situation where letting off the throttle reduces the amount of grip available to the rear of the car to a level below what is required to maintain the current turning pattern. This means that the rear of the car can let go, since the back tires will lose some grip when "weight" transfers to the front of the car resulting in more front grip and less rear grip.
