A VGA connector can support up to 2048 x 1536 but that resolution is called QXGA. The VGA resolution is 640 x 480, which is the sensor resolution of the iPad's front-facing camera.
front-facing = 640 x 480 = 307,200 pixels = 0.3MPixel = VGA
back-facing = 2,592 x 1,936 = 5,018,112 pixels = 5MPixel = >HD
The iPad front camera is called a VGA camera because of its sensor resolution, there is no relation to the VGA connector's supported resolution. It's just coincidence that the new iPad display is QXGA resolution.
Nonetheless, the following conclusion is right:

They can use the same camera that's on the back but it adds to the cost of the device having two. What they probably could have done is have an internal optics switch that changes the direction of the feed to the camera sensor. This way, they don't even need a front-facing camera.
