I'm not seeing where there is a violation of this. On your turn, you can decide when in your move you take off on your jump, and you can decide to jump any distance up to the maximum allowed by your jump check. Taken together, this should mean you can always take off at that distance from your target so that you move exactly the required distance to reach your target, within the limits of your movement allowance. Thus there is no movement after the attack, since any movement beyond the limit takes place on your next turn.
In practice I wouldn't bother getting people to backsolve for the distance from target needed to get the jump right, and just assume they can charge and attack with a jump.
