That's a pretty good stretch but it won't work. If the runner never returns to first while the ball is live but returns to first while the ball is dead it is also to late. The phrase while the ball is live ceases to mean anything in that context.
The supplement is just wrong. The appeal does not have to be made while the ball is live and the phrase should be struck.
