Safe on 2nd, goes back to 1st

Yes ... but Segura is no longer touching the bag about a half second after Braun was tagged. Had Braun not been tagged, he would have been "past Segura" about a half second later.

7.01 comment - once the pitcher takes his position R2 has title to second base and can't return to first. He can't go from being an R2 to being an R1.

A quote that is not exactly a quote... and the part that is not exactly a quote is the part I would disagree with - you've inferred something and then included it in the quote.

Rule 7.01 Comment: If a runner legally acquires title to a base, and the pitcher assumes his pitching position, the runner may not return to a previously occupied base.

First ... Comments are meant to explain the rules, and not augment or change them. Second - many who read this (including the site referenced above) believe this comment is not meant to apply once the pitcher steps off.

More fundamentally, though... the RULE does not state in any manner that the runner cannot, in the normal course of play (for instance, while avoiding a player trying to tag him) move backward beyond a base he is "entitled to". The comment leads one to believe he cannot do this with the ball on the mound. I don't see how one can apply this rule or comment to the OP.

(Further ... apparently neither does MLB!)

I didn't quote anything.
