Simply put, they're lying.
However, something of that shape could be useful to tone down a direct reflection off a nearby surface back into the mic. It could also block some off-axis pickup in a cardioid pattern which could be helpful since the off-axis frequency response of a lot of mics isn't great.
The material it's made of will be important. Sound absorbing materials typically need to be high density, such as acoustic mineral wool. That looks like it's made of foam. Naturally they claim it's foam with magical sound-absorbing properties and who knows, maybe they're right.
