I imagine with multiple objects in a scene it is possible for more than one object to have a vertex at a given point, but with different normals or uv mappings. However, even when I run the algorithm on a single-object scene, the program outputs a unique vertex list that is identical to the original vertex list (with duplicates included). Removing the check for normals and uv coordinates solves the problem. My question for you is: Why do you check all three? If you are going object by object anyway, duplicate vertexes with conflicting texture coordinates or normals should be fairly rare (unless the artist missed a vertex while they were cleaning the model up). I ask purely for educational reasons, I just want to know. Right now I have it checking points only, and I don't want that decision to come back to bite me later. This tutorial has been extremely helpful.
