Nonsense.

The semantics of Mathematica is not formally defined, and its apparent
intent is to do as much mathematics as can be automated. The exclusion
of certain operations on certain operands may change without notice in
the documentation.

If your statement is meant to be read as "unless explicitly allowed
[by the proprietary and secret source code]", then it is vacuous.
Of course the programs do only what the program do;
this is true of any programs whatsoever.

Actually, the syntax of Mathematica is not formally defined either,
but at least that doesn't change so often.
