That wasn't her claim. She didn't refer to sneezing with a mask, nor did she refer to the person behind the sneezer, although everybody in the room with the sneezer benefits by covering it (see below).
The difference to which she referred was the difference between sneezing uncovered and covered. All off the sneeze that ends up on one's palm or in the crook of his elbow is sneeze that ISN'T in the air.
She didn't try. I think she assumed that you knew what I just wrote about sneezes.
You, on the other hand tried to support YOUR position with the following:
Is there a reason you didn't include a link here? I found it at
In the cloud: How coughs and sneezes float farther than you think . This is the first line, which seems to contradict your apparent thesis:
"The next time you feel a sneeze coming on, raise your elbow to cover up that multiphase turbulent buoyant cloud you’re about to expel."
Your link doesn't support the position that masks are ineffective at reducing Covid transmission, nor that covering your mouth when sneezing does nothing. It's about how the amount of a sneeze that isn't captured stays in the air longer and travels further than one might think, and that this time and distance varies with droplet size.
This is also from your link. This is what an unobstructed sneeze looks like:

They didn't include an analogous video of a covered sneeze, but every bit of that sneeze that ends up ends up in your palm or on your sleeve isn't aerosolized into the ambient air.
Here's an article on covered versus uncovered sneezes from

"a hearty sneeze can spew forth droplets at speeds of up to 100 mph, according to
research from the University of Bristol, in England. Particles expelled in a sneeze or cough can carry germs for an array of infectious diseases — colds, the flu, chickenpox, measles and more. To keep from spreading germs this way, cover your nose and mouth with a tissue whenever you sneeze or cough. If you’re caught without a tissue, health experts suggest using the crook of your elbow. That will keep the germs from becoming airborne and will keep your hands from getting germy."
