Did not mean for there to be an additional row of Ninja Pawns, only that the second row of vacant cells be available for the introduction of the five Ninja Pawns. Since this introduction takes up a move, the players might not do such until at least a few of the forward Pawns are developed.
Of course, moving the Pawns to the third rank will deter the forward development of the leapser. But with their additional step movements, they would still have as many or more potential opening cells.
Another aspect, starting from the third rank a few of the Pawns appear to begin the game undefended. Contrary to assumption, this condition is not a negative in itself. But with the ability to introduce the Ninja Pawn, technically they are all potentially defended.
