That's the expected behaviour. Quoting from spec:

If no expression is present, -print shall be used as the expression. Otherwise, if the given expression does not contain any of the primaries -exec, -ok, or -print, the given expression shall be effectively replaced by: ( given_expression ) -print

Yes, I wasn't implying the behavior is wrong. Was just mentioning it. Anyway, thanks for that link, which explains why. That Open Group info on POSIX utilities is a great resource for when you want to know the comprehensive, well-specified behavior of the commands.
