Rules Experts: The lack of a runoff after illegal shift

Can we have a discussion about this actual rule, and not what happened in the game?

Up until last night, my understanding was that the following circumstances would lead to a 10 second clock runoff:

Clock under 1 minute + Clock was moving prior to the start of play + no timeouts for offense + offense gets a penalty

The intent and spirit of the rule obviously being so that the offense doesn't get an advantage of stopping the clock by committing a penalty.

Now after last night, it appears the above only applies to dead ball penalties, not all penalties. I'm having a really hard time understanding why, and would appreciate an explanation for what I'm missing.

I've seen a few different rules quoted as the applicable one to last night's game. I'm not sure which is correct, but I have problems with each of them:

quote:

---

b. The 10-second rule does not apply if the game clock is not running when the foul occurs or if the foul does not cause the game clock to stop immediately (e.g., illegal formation).

---

Don't all fouls cause the clock to stop immediately? I get that this is probably referencing dead-ball fouls that kill the play. But the clock stops after all penalties, at the very least to announce the penalty.

quote:

---

4. Team A players all set for one second, then A22 and A33 start in motion (no false start). At the snap, A22 has been set for one second while A33 continues his motion. The ball carrier
is tackled inbounds short of the line to gain.
RULING: Team A live-ball foul, illegal shift. Five-yard penalty.
There is no 10-second runoff because the foul itself did not cause the clock to stop. Play clock: 25 seconds.
Game clock starts on the referee’s signal.

---

This one is especially important because it specifically references being tackled in bounds short on line to gain. In other words, the clock would still be running if not for the stoppage to announce the penalty.

"The foul itself did not cause the clock to stop"

Then what did cause the clock to stop? Because the ball carrier was tackled in bounds without achieving a first down, and the clock is running. If the foul didn't cause the clock to stop, then what did?

As far as I can tell, the gist of the rules seems to be only dead ball penalties result in the runoff. It seems to me there is potential here for the offense to benefit from committing a penalty to stop the clock. Example:

8 seconds left, Offense has no timeouts, completes a pass in the middle of the field. Ball carrier is obviously going to be tackled in bounds, time is likely going to runout before the ball is snapped. Offensive player sees all of this, intentionally commits a live ball penalty(holding, facemask, block in back, whatever). Ball carrier is tackled with 00:02 left on clock. Clock stops for officials to announce penalty. During the stoppage, offense gathers itself and is ready to snap the ball as soon as official signals ready for play.

The offense gained an advantage by committing a penalty there, correct?
