I noticed that many people wear these visors instead of masks, often at an angle such that it barely comes level with their chin, and wonder how on earth that's providing any protection for the wearer or whoever they are projectile-breathing at. Can you explain?

I can't explain, since unlike some, I'm not so smug to consider myself an expert following a twitter visit. ;)
Go to a Men's Shed or similar and operate a metal grinder. Learn the power of hard protection.

As with any form of protection, it needs to be approprately fitted and depends on the person using it properly.
Nothing is certain with CV19 and opinions vary considerably, but after Googling for a bit, the consensus seems to be: a visor appears to provide more protection for the user, than a mask, but isn't as effective at preventing the user spreading the virus. It helps to protect the wearer's eyes from virus-laden droplets and should also reduce spread to some degree by reducing the momentum of a cough or sneeze, but the bottom is still open, so some of it will fall onto objects below.
Ideally people should wear both a visor and a mask, but if someone can't wear the mask, then they should wear a visor. I would think a long visor, extending well below the chin and a scarf around the neck, to fill the gap, even if it doesn't cover the face, would also provide more protection to others, by stopping droplets from falling on surfaces below.
I think my motorcycle helmet will protect me more than a mask and should also do a decent job of preventing me spread it, as it's well-fitted and there's some fabrick under the chin. Lots of this seems to be common sense.

It all depends how you keep your hands away from these barriers.

A visor should do a better job of preventing someone from touching their face, than a mask, which will harbour the virus, when it becomes damp.
I'm not sure if that makes that much difference though. It's true, people touching their mouthes and noses helps spred the virus and was originally believed to be the main mode of transmission, but now droplets suspended in the air is thought to be more likely.
