Avigilon H4 PTZ 1MP 45x Optical Zoom Does Not Make Sense

Avigilon has a new H4 PTZ 1MP camera that claims to have 45x optical zoom. What's up with that? 45x optical zoom in a camera that has a 4.3 to 129mm lens? How? When we say something as X optical zoom, isn't it related with the focal length of the lens? So shouldn't it be 30x zoom (4.3x30=129)? Or shouldn't it have a lens of up to 193.5mm (4.3x45=193.5)?

And the 2MP version of the same camera with the exact same lens has 30x zoom. What? Any thoughts on this?
