ASA rule Number for dropped 3rd strike

Question
Mark, I asked you the series of question re: double sided first base the last day and half.  In presenting the answer to the league, coaches are asking for the ASA rule number that covers the positioning of first baseman for throw on dropped 3rd strike so they can read up on it as well as provide it to the director of your youth umpire program.  Thanks.

Answer
Hi John,

nice to talk with you again, here's the rules but if someone is looking for the rule to exactly say F3 can take a position on the colored portion if.....you're not going to see that


8-2-M. The double base shall be used at first base in all divisions of play. The following
rules should be enforced:
1. A batted ball hitting or bounding over the white portion is fair.
2. A batted ball hitting or bounding over the colored portion is foul.
3. When a play is being made on the batter-runner, the defense must
use the white portion and the batter-runner the colored portion of the base.
EFFECT: The batter-runner is out when there is a play being made at
first base and the batter-runner touches only the white portion, providing
the defense appeals prior to the batter-runner returning to first base.
Once the runner returns to the white or colored portion of the base, an
appeal shall not be honored.
4. On any force out attempt from the foul side of first base the defense
and the batter-runner may use either the white or colored portion of the base.
5. On an errant throw pulling the defense off the white portion of the base
into foul ground, the defense and the batter-runner can use either the white or colored portion.
6. On balls hit to the outfield with no play on the batter-runner advancing
to first base, the batter-runner may touch the white or colored portion.
Should the batter-runner return, the runner and defense can use the
white or colored portion.
7. When tagging up on a fly ball, the white or colored portion of the base
may be used.
8. (Fast Pitch, Slow Pitch with stealing & 16-Inch Slow Pitch) On an attempted
pick-off play, the runner may return to the white or coloredportion of the base.
9. On plays at 1B when the batter-runner touches only the white portion
and collides with the fielder about to catch a thrown ball while on the
white of the base.
EFFECT M-9: Interference, the ball is dead, the batter-runner is out and
runners must return to the last base occupied at the time of interference.

The key is 8-2-M-4 stating the defense can use either the white or the colored.  What does "use" mean?  Full use in my opinion including setting up or taking a position on the colored portion.
