How many experienced officials would think they have to explicitly state the ball returned to the player's hand?
Not sure about the relevance of either of these questions, but bottom line, the ball does have to return to the hand, both on a written test, and in a real game, for this to be a violation.
Any official that calls this violation when the ball first touches the backcourt, without waiting for the next offensive touch, could be open for a little criticism, maybe not from most fans, or from inexperienced officials, but from experienced officials observing, or a few knowledgeable fans, or perhaps even a few knowledgeable coaches, especially if the ball takes an odd bounce and bounces a few feet away from the dribbler, untouched, into the backcourt.
Even little kids seem to know the rule. If one officiates little kids long enough, eventually one will observe a little kid, who in this situation, knows that they can't be the first to touch the ball, so they follow the ball closely, with both hands ready to grab the ball after an opponent barely touches it. This, or course, never works. The dribbler either grabs the ball first, or the opponent grabs the ball first. I've been playing, coaching, officiating, and observing basketball games for fifty-five years and I've never observed this "play" work. Never. Ever. But it's always fun watching little kids try it. And, maybe, someday I'll see it work. There can always be a first time.
I've observed high school players, in this situation, avoid a backcourt violation by following the ball, but not touching it, oddly choosing an out of bounds violation instead of a backcourt violation, sometimes leading to an oddly advantageous throwin for the opponents.
Regardless of the frontcourt status of the feet and the ball, this play (original post above)
as written (before bbcowboy's Post #14 additional information), is never a backcourt violation. The ball touching the floor in the backcourt (alone) does not make this a backcourt violation. Something else (an offensive touch), unwritten in the original post, needs to happen for this to be a backcourt violation. If it's a controlled dribble, it's probably going to happen (offensive touch and thus, backcourt), but if the dribble takes an odd bounce and bounces a few feet away from the dribbler, untouched, into the backcourt, it doesn't become a backcourt violation until that offensive touch happens, so, in this specific case, it's important that officials don't sound a premature whistle.
