According to Article e on page 34 of the original NBA rules, there is a paragraph about the fengshui ball rules:
“When a player loses control of the ball due to the following circumstances, he can make a second fengshui ball:
1. When shooting, the ball touched the rebound or rim;
2. The opponent touched the ball;
3. Pass or miss, and the ball touches the rebound or rim or has been touched by other players.”
——
According to the above rules, Butler cut the ball at fengshui ball this time (that is, the “touch” in Article 2 of the above rules), Butler temporarily lost control of the ball, so Butler can start fengshui ball again after taking back the ball right. Then, the action of “taking the ball back” naturally conforms to the rules.
