It doesn't, it just avoids the need for an intermediate type.

What I meant was that it might be strange to require a cast on the
result of a function call, because we don't really do that anywhere
else. Florian pointed out that it's common to require casting the
ARRAY[] constructor, so that has more of a precedent. I'm not really
sure how much that matters.

I'm OK with the intermediate type, but Florian seems skeptical of that
idea.
