[DaveASA/FED]

as already mentioned 8.7 is the Look Back Rule. Each article goes on to explain an additional aspect of said rule. you quoted art. 1 already, art 2 says runner, art 3 runner, art 4 batter-runner.

If you read these articles in whole and take all these items into account you will understand when to call the lookback rule and what actions will result in a runner or batter-runner being called out for a violation of this rule.
