ruling from referee magazine

[shawnwil]

I was at a clinic on last night, and one of the officials showed me a ruling from Referee magazine about 2 issues ago. The play was there was a shot, that hit the floor, and then bounced off the floor, and the horn sounds, and then it goes in the basket. The ruling of referee magazine was that the basket counted, and award 2 points. My problem is once the shot hit the floor, the shot was over, and when the horn sounded, the play ended. I am making the assumption that the horn that sounded was for the end of a period or quarter. Does anyone understand the ruling in referee magazine or know what they based it on?
