Swords are disjointed. Attacks like Dedede's B-air aren't disjointed as the actual body of the character is used in the attack. You can't attack Marth's sword and hit him, but you can strike Dedede's foot and hit him. The problem with Marth's attacks is that the hitbox is open for a very short duration, so a character can maneuver just out of range, wait for the sword to come down then move in and hit fast between attacks. That's why its a good thing to watch your opponent, so if you miss your not moving right into their counter attack.
