This is technically true since 4.41.4 says "the try ends when the throw is successful, when it is certain the throw is unsuccessful, ..."

But I think it's easier to explain from the angle of it being clear that the try was unsuccessful. (short of the rim, CLEARLY wide of the goal).

It's really just wordsmithing but I think starting down the path of saying the defensive touch made it go opens you up for more questions than just explaining the try had ended.
