This isn't just slightly wrong—it's totally wrong. All you have to do is look at a tear down to see that there are far more than 9 microlenses (which do not correspond to different focal lengths). I highly recommend that you read Ren's dissertation again before you speak authoritatively on the subject again. I'm not sure how you could read it and come to the conclusions in this post.
Also, I'm the person in the video you posted. Please let me how I "tripped up."
