No, it looks like those are near the middle of the body, you see it near the end of the tail. But you have to remember that pied markers aren't always acurite, normals can have the 'marker' and some het pieds won't have the marker.
I put up a thread of my three het pieds with their belly shots. You can see that the markers aren't very noticeable, and the average person would probably pass them off as normals. The first one is a double het 100% het albino, 100% het pied, the other two are 100% het pied.
