The "Follow" modifier points at the Hot Point of the object so I suspect the Hot Point for the figure doesn't move since this is an imported file. So, there are a couple of ways to fix this: 1) Change the Point-At modifier to track one of the articles of clothing on the figure, or 2) insert a Target Helper Object (THO) and animate it's movement to imitate the Figure, then use the Point-At on the THO.
