Consider this:

1. Team A initiates a fast break and A1 receives the ball just before the half court line. There is one transition defender B1 ahead of A1
2. Why doesn't A1 just throw the ball forward towards the basket, beat B1 with pace, catch it after one bounce and finish the lay up? I mean this is considerably easier to do than dribble all the way and use skill to beat the defender, isn't it?

As noted by SNIPERBBB AND Cameron, above, that initial throw of the ball constitutes the start of a dribble. If A1 then catches the ball, it is the end of that dribble, and pivot foot limitations/travelling limitations come into consideration.
If A1 continues the dribble, without catching the ball, such action is legal. If, after catching the ball, A1 starts a new dribble, the dribble limitations - double dribble rules - are in consideration by the covering official.
