The OMD has more total photosites than the G3/GX1 sensor. The difference is small but quite important. You cannot just trim a sensor here or there and call it the same thing - it makes zero sense to go to the trouble of changing the chip design over a few thousand pixel sites and not tweak other more performance-related parameters as well.

The image forming area is less than the total area, and it is quite common for companies using the same sensor to choose slightly different border masks. For instance, Nikon's and Sony's often have different pixel counts. One reason is that different companies pattern noise measures need different numbers of black masked pixels.

how dare you question a dude who "knows anything about chip fabrication" !!!

You get 16 effective megapixels from a GH2 because every aspect ratio mode constitutes a 16MP crop of the sensor. The OM-D has 16.9 MP in order to provide 16 total megapixels during sensor shift IS.
