Batting Position

[Bandit]

ASA. Rule 7 Section 3 A. PRIOR to the pitch, the batter must have both feet completely WITHIN the lines of the batter's box. The batter may touch the lines, but no part of the foot may be outside the lines PRIOR to the pitch. Straight from the book..Am I missing something or does this rule go against itself. This came up in a FED game and the FED book ( Rule 7, Section 1 Art 1) only says WITHIN the lines. I was looking to compare and found this wording confusing
