Passed Base runner question

[cpa]

I have a different way of looking at this question of whether or not a runner has passed another

If I understand this correctly, we have a "front" runner who has retreated toward 3rd, which is now occupied by the "back" runner. The front runner reaches 3rd, touches it, and continues on down the third base line while the back runner continues to maintain contact w/ third base.

At that point -- I've got a passing -- using the following logic. If both of those runners now desire to score, who is closer to scoring? The back runner has already MADE 3rd base and may run home without retouching 3rd -- because they're in contact with it.

The front runner is farther away procedurally from reaching home -- prior to running home they must legally retouch 3rd, a process not required of the other runner.

Since the front runner's position is now farther away from home than the back runner (a reversal of the original order) -- I've got a passing -- and an out by the person who did the passing -- the back runner.
