I also cannot think straight

I'm confused on the "fumble rule" and would love a ruling as I cannot find anything in the HS rule book except the definition and this does not help interpret certain plays.
Play - A1 finishes his dribble, looks to throw the ball to another player but stops his throw as the other player breaks the other way and it fumbles out of A1's hands onto the floor. A1 takes 2 or 3 steps and pick up the all. He does not dribble again, he just picks it up. What is the ruling?

There is nothing in the case book now but I remember from a past case play that if the ref deemed it to be truly a fumble (and not a pass that he goes and gets because the other player broke the other way), he or she may go pick it up because you cannot walk or double dribble when you have no player control.

What is the ruling?
