Meteorological truism #54: No matter where you're raking the leaves to, the wind will automatically change direction to blow them in exactly the opposite direction, generally as soon as you've gotten them neatly in a pile to be bagged.
Meteorological truism #67: The leaf bags will not stay in place (see truism #37), particularly when you are first trying to fill them. Holding the bag open with your feet and trying to rake the leaves into it by sweeping them in through your legs is inefficient and only serves to amuse the neighbors. (See also: futility)
