Has he ever done this? I mean, have the tip go after Link if he slide to the side before the crack? Merely being an extension of oneself isn't adequate proof for that.
through ought the fight he adjusts the length of his whips so that Link cannot get out of range, or get too close to be whipped. This is also how a whip works normally, the fact that Majora's are pehensile only helps his case.
What page is this video of him dodging the whip crack.Technically if what you say is true then Majora would have to teleport his whip everywhere (To achieve changing the point it would crack at). He didn't control them like arms, he controlled them like Whips.
The video is of a normal person changing the direction of a cracking whip rapidly. And he controlled them like whips, yes, but whips which he had INCREDIBLE control over, even picking Link up and throwing him, adjusting their length, attacking repeatedly at rapid speed, ect.
