Basic Spot

[whitehat52]

No this doesn't change the enforcement spot. Although you may have more than one spot of enforcement during a running play (each time a penalty is called it has a related spot of enforcement where the run ends), you may have only 1 loose ball play during each down. Even though you first had a loose ball in advance of the neutral zone, when A recovered the loose ball and retreated behind the line of scrimmage and fumbled, this fumble caused all the previous action to be part of a loose ball play. The foul occured prior to the fumble behind the line of scrimmage, so the foul is part of the loose ball play. If B accepts the penalty it will be enforced from the previous spot, if they decline it will be a touchdown for A.
