Runner on 3rd; Batter walks, continues to second?

[SethPDX]

Using NFHS (ASA might be similar):

What you have to keep in mind here is the look back rule (LBR). Once the B/R has touched 1B and the pitcher has the ball in the pitching circle without attempting a play on any runner, the LBR is in effect. With the rule in effect:

If the runner comes back to and touches 1B she must stay there.

If the runner is off a base, once she stops she must make a choice of which base to go towards. She cannot change direction after she makes the decision.

There are some rules that specifically cover a B/R overrunning 1B.

If the pitcher has the ball in the circle before the B/R turns around, the B/R would have to return to 1B.

If the pitcher has the ball in the circle before she turns toward foul territory, once she turns right she is committed to 1B.

So this is slightly different than 1. (which is a contuous run toward 2B), but is at first heading back toward 1B, before sudden turning to head toward 2B. Is that ok?

If the pitcher has the ball in the circle before she turns back to 1B, she is committed to 1B.

I think I got this right but I will get corrected if I'm wrong...
