I don't think the asymmetry is a conscious design choice.

As I recall, SELECT was designed early on, and ORDER BY
came later. We don't have any requirements for expressions
in select, and aside from the occasional thinking-out-loud
here or there, none of the WG discussions have argued
for a change, so it hasn't been changed.
