From that I infer that from the time the official is ready (the earliest moment associated with any jump ball restriction) until the jump ball ends, the restriction on the jumpers in 6-3-1 is in effect. Thus, it is a violation in its own right. However, a similar inference may be drawn, and drawn a little more easily, from the note under 6-3-8.

So if a jumper comes down with his foot over the line before the ball touches a non-jumper, you call a violation?
