Because that is the way it was designed (parallel sizeof).
That is a known issue -- look for lengthy discussions on the boost
mailing lists. For the future, C++ will support reference- and
non-reference-preserving type queries.  Look for the last papers on
this issue (the last revision have splitted the auto proposal -- much
like typeof except you don't have to repeat expressions -- and
decltype -- much like typeof but preserves refernces).
