MeshFaceList.DeleteFaces also deletes vertices

MeshFaceList.DeleteFaces also deletes vertices, however the SDK says it maintains the rest of the geometry:

“Removes a collection of faces from the mesh without affecting the remaining geometry.”

It seems to happen when a vertex loses all its faces.
Since there is a method to remove unused vertices, this method shouldn’t change the topology in my place.
