There’s an upvoted sub comment to that which has a good correction. That statement as a whole is just not true and a meaningless statement. When you pass an orbiting body you will take some of that body’s orbital momentum and add that to your current momentum. There’s really no semantic argument in my mind that could justify the above statement. You change direction because you have more in total. There’s no bending of the direction here, just addition of new vectors but that’s exactly how all acceleration works anyway so it’s a bit meaningless to make that statement and I’m really not sure what they are trying to get at. Maybe from the pov of the orbiting body there’s no change but that’s not the thing anyone cares about when doing a flyby.
