From the picture and looking at the holes.
If the holes are in the right spot.
Looks like it would push a bit of that ring of fire & sparks off the wheel, instead of it spraying back onto the cutter.
I expect it also keeps a layer of cooler air on the wheel in the work region.
I'd also bet a dust mask is more desirable while using it now.
