On the Purported "Projection-Operator" in a Specific Modified Epstein-Glaser Normalization Subtraction Scheme

We show that a modified Epstein-Glaser (EG) normalization truncation operator Twpresented a couple of years ago is, due to an automatically emerging cascaded sub vectorspacestructure, not a an automorphism on the vectorspace S(R^m) of Schwartzfunctions, in contrast to theoriginal EG-operator W. Apart from the (rather simple) proof itself, we hint on the origin of thedifficulties with using T_w instead of W.
