Continuing action

[greymule]

I think that some of my difficulty with certain case book plays is a result of not understanding this term. Exactly what does "continuing action" mean?

Fed case book 8.2.3: B1 hits a slow roller to F5 and arrives safely but misses first base. F3 catches the ball and casually steps on first base, though he believes the runner has beaten the throw. Ruling: B1 is out. Because a force play is being made on the runner and is the result of CONTINUING ACTION [my emphasis], F3 is not required to appeal the missed base and needs only to complete the force out.

We have already discussed the infamous Situation 19 where the runner who missed second on a force play is "accidentally" tagged out after arriving safely at third. That also must be considered continuing action.

If B1 hits a ball off the fence, misses first base, and is safe at home because the catcher's tag is late, would B1 still be out on that accidental force play appeal? Or does something to do with continuing action negate that out?

If the catcher had handed B1 the ball as a souvenir for his inside-the-park home run and in doing so "tagged" B1, would B1 still be out?

Can anyone give me a play where there's NOT continuing action? How about a play in which the lack of continuing action would negate the "accidental appeal" on a force?
