Merge simply adds everything in the same model: in your case this results in an
invalid resulting mesh (you can reproduce the same behavior in the GUI). To
fuse two grids, you would need to make sure they don't contain entities with
clashing tags, then remove the duplicate vertices
(m->removeDuplicateMeshVertices()).
