To me, that sounds like one of two:

Either, the C/C++ scoping/life time rules apply to the source code only and how it 'conceptually' is executed, and does not relate to the compiled code and how it actually runs.

Or, the C/C++ standard does not, strictly speaking, allow optimization of the kinds that we are talking about here, such as allocating a variable in a register, reuse of stack locations within a single scope, or removing variables entirely.

I don't know which is correct. To me, it is the running code that matters, even if the correct interpretation of the standard is that it doesn't care about the generated code.
