Why is this a kicked ball violation

An alternate angle of Wemby's kick with the game timer Doesn't look as intentional as from the other angle first posted

For those of you said this is not a backcourt violation read the text and explain please I'm genuinely curious

Jose Alvarado committed backcourt violation right here

In a tie game with 20 seconds left Collin Sexton calls for the ball but is waved off demonstrably by Isaiah Collier who ends up getting an 8 second violation This leads to a HEATED exchange on the bench Give me the fing ball

A questionable no backcourt violation call with 06 secs remaining in regulation There is a jump ball between Lester Quiones and Chris YoungbloodQuiones moves away on the jump ball lets Youngblood tap the ball to him He misses the potential game winning halfcourt shot no foul

A rare two 3-second defensive violations on two consecutive possessions
