This was changed a "few" years ago to add the BR touching 1B part. Before that, the LBR went into effect for R1 (in your scenario) as soon as F1 had possession and control in the circle.

Now, both conditions are required if there is a BR: possession and control by F1, and BR touching 1B (or being put out). But, once both conditions are in place, R1 had better be making a move and quick if she is off the base, and must stay on 3B if she was not off the base.

The “Look Back” rule shall be in effect for all runners when the ball is live, the batter-runner has touched first base or has been declared out, and the pitcher has possession and control of the ball within the pitcher’s circle....

ASA 8-7-T-2

Once the runner stops at a base for any reason, the runner will be declared out if leaving the base.
