I get what you all are saying and again, my question has nothing to do with obstruction. It was simply regarding running in reverse toward home plate and if a rule applied. This interpreted rule is a standard across all leagues of baseball. Run downs (reverse running) are allowed between home and first, the runner is live until tagged or forced at first or happens to contact home plate. If you look at that second video post, the interpretation was incorrect.
Thanks for all your input!
