GR III x lens combines two different focal lengths??

The GR III x website product description says something interesting about the lens:

"users can capture an image similar to those taken at a 30mm semi-wide angle or create a completely different visual expression as if taken at a 50mm standard angle."

What exactly does this mean? How can a 40 mm eq. lens capture a scene similar to a 30 mm lens? That suggests the GR III x lens is actually quite close to the GR III lens.

Even if this is true, how can the same 40 mm lens capture a scene similar to what you can take with a standard 50 mm?

That's like two lenses in one! And if this is true, then why isn't it true for a stadard wide like the common 35 mm eq. FL?

Also, how is 30 mm semi-wide angle? I thought wide angle starts from 35 mm and goes to 24 mm. Wider than that and you get ultra wide-angle.

Quite curious! Thanks for you thoughts.
