I'm genuinely struggling to see what is unclear about this question about snapping the ball? It seems like a perfectly simple, clear and answerable question to me.
I agree. The question was perfectly clear, if one has any awareness of what the words involved mean in that context.
If one doesn't have such awareness, they should seek clarification, or better, explore the context themselves. This would make them more able to handle similar questions or other questions in the same context later, and perhaps even find the answer during their inquiry.
If one does have an awareness, then closing it as unclear is dishonest and unhelpful. Either address any misconceptions in the question, or explain the relevant rules or protocols or traditions in an answer, or downvotes and ignore.
