in (2) the one knee down and retrieve the ball scenario, wouldn't it only be traveling if she not only picked up the first knee, but also put it back down? Or started a dribble after picking it up?

The way I am reading it, it sounds the same as if a player were to catch the ball while standing on one foot. Putting down the other foot and picking up the first one is okay, it is putting the first one down that causes the violation or starting the dribble with that foot off the ground.
