When using aggressive block it states :
You push back as you block the attack, knocking your foe away or off balance. You use your shield to push the triggering creature, either automatically Shoving it 5 feet or causing it to become flat-footed until the start of your next turn. The triggering creature chooses whether to be moved or become flat-footed. If it chooses to be moved, you choose the direction. If the Shove would cause it to hit a solid object, enter a square of difficult terrain, or enter another creature’s space, it must become flat-footed instead of being moved.
My question is in regards to the chosen direction of movement if the creature chooses to move. Can this movement be any square around the creature or does it have to objectively be further away from the point of origin of the shove?
