It's interesting to me that you focus on the 'high' meaning of sewi, because I've always focused on the 'religious' or 'divine' meaning. So I would hear "lawa sewi" as something like 'religious head' or 'religious leader'. Probably my first parse of "soweli pi lawa sewi" would be 'the rabbi's cat' or something, rather than a giraffe. Or I would imagine an animal whose head is similar to some concept or representation of divinity. :-)
