Maybe a little bit, but I'd think you'd want barriers that are at least head-height if you wanted to to that.
It keeps your neighbor's shit from spilling over onto your desk, necessitating an awkward conversation (at the minimum). It also gives you a surface to attach taller, jury-rigged barriers, if you're so inclined.

But the longer I look at the picture, the more I realise that they have more personal space, sound isolation and visual privacy than I have in my office.
Now imagine half of them being on the phone....terrible.
