In any reasonable implementation, it does.

The only wrinkle is that some implementations promise that an
immediately-following realloc() on the freed block will work, but
the freed block IS available immediately for re-use; this is just
a special weird case of re-use.  A malloc() after a free() is
expected to be able to return a pointer to a block containing
some or all of the freed block.
