Here is part of what I said in that link:

"For each frame, all of the photodiodes must be sampled and each pair combined for the final output. That is 40M x 7 fps = 280 megasamples per second available to the processor. Near double the rate for 7D."

Yes, but that isn't true, the camera doesn't have to sample the whole sensor for AF, it just does windowed readout, reading out the AF points only. Then for the main capture, the two sub-pixels are binned on the chip. There is only one readout transistor per full pixel.
