Sorry, but you are contradicting yourself.
If the photons in sub-frame A don't disturb the photons in sub-frame B when sent at the same time, and vis versa, then the math for the whole frame is very simple. The distribution of photons for the whole frame is the distribution of photons for sub-frame A plus the distribution of photons for sub-frame B, whether they go through the lens at the same time or not. Yet you claim one method will magically cause the overall images to change (with more blur).
Also the data density for the lens is the same either way too, since the data density for the lens elements is in photons, not in pixels.
If each sub-frame with eShift as we know it is 1x10^17 photons per 1/120th of a second, then if you split the light in half to send both sub-frames at the same time then the data density for the lens is still 1x10^17 photons per 1/120th of a second.
The only way you could be right is if the sub-frames interfered with each other, but you now may now understand that the interference factor between the sub-frames when sent at the same time is essentially zero.
BTW: This was another post you made that you would understand was wrong if you understood how you could take a picture of two light bulbs and have it be the same whether they were on at the same time or not.
You are missing the basic understanding of light and lenses to be able to answer questions correctly that you are answering based on your instinct about how light and lenses work, instead of on facts.
