Right, and you and I are probably in agreement on what that means but this is league and any vagueness to the rules are interpreted to one's own advantage then argued beyond reason.
Here's how the argument would play out.
Me: Those are considered down. You lose.
Opponent: No, the rule says "Drop them in and resume playing the game unless the pocketing ends the game." The pocketing would end the game so you don't drop them in. Good luck with that out.
Me: No, no, the pocketing ends the game so you don't resume playing. The game is over.
Opponent: If you actually read the rules it specifically says: "Drop them in and resume playing the game unless the pocketing ends the game." The "unless" negates the "drop them in." Resume playing.
Me: The "unless" negates "resume playing" because the game is over.
Opponent: Resume playing.
Me: Drop them in.
Opponent: RESUME PLAYING!
Me: WHAT'S MY OUT?
I can almost guarantee you this exchange has taken place in some form in some APA match.
