As you naturally apply rudder to keep the aircraft tracking straight, and this becomes an almost reflex action, it’s not until you are made aware of this particular phenomenon and think about what your feet are actually doing that it becomes obvious that this is what happens on most occasions.
The 787 also has this trait. I always put it down to the surface area of the large nacelles being blown downwind.
