Though, it is a sideslip but airplane actually doesn't slip in the direction of lower wing because of the crosswind pushing the airplane back on the desired track. This technique is not recommended by Airbus because the bank angle required to fly the steady sideslip is large and places the airplane close to the geometry and roll/rudder limits. Excessive bank angle close to the ground may lead to wing/engine scraping the ground.
