Yes, my compound doesn't support groups as I explained in the video. This is because ICE can't deal with separate meshes from a group.
About the sample scene, as explain in the video, to match the original point cloud you must use the same ID (in a compound that I don't remember the name :) ). Again, I never test seriously this compound so it is maybe buggy. But anyone can improve it and share it.
