rounding first base after a walk

Question
I'm unclear with the rule!! When the batter gets to first base on ball four, I've been told that if a batter rounds first base on a walk, and stops she is declared out!! Is this the correct call?? Even if she goes right back to first she was still declared out.

Answer
Hi John,

If the look back rule is in effect

A b-r walked can legally round the base stop once and immediately advance to the next base or return to 1st base.

If they over-run 1st toward rt field and turns left and moves directly toward 2nd , they must attempt non stop to advance to 2nd

If they over-run 1st toward rt field and turns left and stops, they must immediately move non stop back to 1st or to advance to 2nd

If they over-run 1st toward rt field and turns left and moves back toward the infield in any direction other than directly toward 2nd, they must immediately move non stop back to 1st

If they over-run 1st toward rt field, turn right, is committed to return non-stop to 1st.
