This was the only case play I found concerning CO on a squeeze play:

8.1.1 Situation G: R1 is on third. R1 starts home as in a squeeze play. F3, who is playing close for a bunt, cuts off the pitch and tags R1.
Ruling: This is treated the same as catcher obstruction. The ball becomes dead at the end of playing action. The coach or captain of the team at bat has the option of the play or penalty. If the penalty is accepted, R1 is awarded home and B2 is awarded first. (2-36)



Here is the rule:

Rule 8: Batter-Runner and Runner
Section 1: The Batter Becomes A Batter-runner
Article 1


Art. 1... A batter becomes a batter-runner with the right to attempt to score by advancing to first, second and third and then home plate in the listed order when:
a. she legally hits a fair ball.
b. (F.P.) the catcher fails to catch the third strike before the ball touches the ground when there are fewer than two outs and first base is unoccupied at the time of the pitch, or anytime there are two outs.
c. an intentional base on balls is awarded (S.P.), or a fourth ball is called by the umpire.
d. the catcher or another defensive player obstructs, hinders or prevents the batter from striking or hitting a pitched ball.
e. The catcher or any other fielder shall not:
1. Step on, or in front of home plate without the ball, or
2. On a swing or attempted bunt, touch the batter or her bat with a runner on third base trying to score by means of a squeeze play or a steal.
PENALTY: (Art. 1) The runner would be awarded the base on the attempted steal or squeeze. The batter shall also be awarded first base on the obstruction and the ball is dead.

I think the ruling for 8.1.1.e.2 is assuming that the ball was not put into play by the BR. It is missing a portion of the rule that ASA contains.
