Well GATOR is not doing a 1:1 copy of the shapes, it's reinterpreting every point by the transformation of each individual closest triangle using pointlocator/locations magic, a.k.a. barycentric coordinates<http://alokgandhi.com/blog/2012/05/28/barycentric-coordinates-and-the-magic-of-locations/> sorcery math.
Unless your meshes are completely and absolutely the same volume there is always a chance of slight error, unfortunately.
