This rule was originally written when home plate and the batter's boxes were entirely in foul territory. When the playing field dimensions were changed to what we have now, home plate in fair and part of the batter's boxes in fair, the rule was never changed to reflect the field changes. The current interpretation for OBR is that the batter must have at least one foot on the ground, entirely out of the batter's box in order for this rule to be enforced.
