Why Is Ubiquiti Image Sensor Pixel Count Vs Resolution Different?

I am putting together a bid for the below listed spec on the camera.  After questioning why they are choosing a particular manufacturer and pointing out that the camera does not have 3 MP resolution, they pointed out the fact that the imager is actually 4MP even though the resolution is only 1080.  I suppose that may meet the spec but why would anyone do that? I am curious as to what advantages or disadvantages.  The manufacturer in question does not have any cameras above 1080p.  And would you bid it under those specs?  It doesn't feel right to me.
