They deleted "not higher than the batter's head" because it was misleading and confusing. The batter's head was actually never the defining criterion. The wording was intended to indicate that if the ball rises over the batter's head, it can't be a foul tip, but it led people to believe that (1) if it didn't rise over the batter's head and F2 caught it, it had to be a foul tip, even though a case play contradicted that notion, and (2) if F2 did catch it over the batter's head, it could not be a foul tip, which is not true. (A batter could swing and nick a pitch over his head, and the ball could go sharp and direct into F2's outstretched glove—an obvious foul tip but still over the batter's head.)
