Ball thrown off backboard

[Scrapper1]

Case play 9.5 makes it clear that it's legal to end your dribble, throw the ball off your own backboard, and then catch it.

I was asked today about this variation.

Player ends his dribble, throws the ball off his own backboard, the ball then bounces on the floor, and then the player recovers it.

Because the ball hit the floor, is the throw considered to be the start of another dribble? (The dribble begins by throwing or batting the ball to the floor. . .)
