What you're missing is that the time (and number of times) the macro is
expanded depends on various factors.  The Elisp interpreter by default
only expands macro during execution (and throws away the result).
But don't rely on it, because the byte-compiler does it differently, and
the evaluator could also be changed to do it differently.
