Interpretation.

NFHS rules only.

Al is dribbling down the sideline in the front court at the foul line extended. B1 is defending and causes A1 to pull up their dribble by straddling the sideline (one foot inbound and one foot out of bounds) effectively shutting down any dribbling lane. There is no contact but when A1 pulls up their dribble, B2 comes from behind and steals the ball from A1. Is it a violation under the new NFHS rules to have one foot off of the court or do you need to put both feet off the court for an unauthorized reason for leaving the court?

Suppose in the same situation, A1 hadn't stopped, but continued and made contact with B1. The result would (usually) be a blocking foul, and not a violation. See 4.23.3B

Assuming (and this might not be a valid assumption) that the NFHS did not leave the case in the book in error, I think we can assume that one foot OOB is not a violation on the defense, and your play stands.
