You did see the analysis where the force of the sneeze blows particles out the back of the mask and up around the eyes and sides, right? It almost makes the sneeze stronger because it concentrates the stream and forces it though these small openings.
In addition, it also concentrates your own breath, so any possible contagion (it keeps out nothing the size of a virus) is concentrated and rebreathed repeatedly, this giving you the heavy viral load you need to get a really bad case.
The mask is a talisman and nothing but, and in fact will probably be acknowledged as harmful.

The case of the 2 infected stylists is hard to ignore.
