What's happening here is that the `#%module-begin' binding from
`racket/base' calls `local-expand' on each of its forms, to determine
whether its an expression or not.  This implements the printing of
top-level expressions.  If you replace `#%module-begin' with
`#%plain-module-begin', you should see the desired behavior.
