In that example, yes, but not always, and splicing-parameterize can’t
be sure one way or the other. In this example, containing exclusively
definitions is completely legal:

    (let ()
      (splicing-parameterize ([my-param #t])
        (define x (my-param)))

I suppose it would be possible to force users of splicing-parameterize
to make the final body form an expression, but the other forms from
racket/splicing don’t have that restriction, so it would be a bit odd
to have different behavior here.
