Lets clear up one thing here: The G uses H4 hi/low bulbs for the fog lights, and these are bulbs that can only do low or high - that is the only reason why the G has either fog light or high beam and never both. Since fog lights, driving lights, and high beams all focus light on different areas, having them all on at the same time will not hinder lighting performance of either high beam, low beam, or fog light as long as they are running on separate bulbs.
Maybe H4s are only capable of one filament running at a time, but if you look at any car with OEM fog lights you will notice that they turn off whenever you put the high beams.
Fog lights does hurt distance vision. They are mostly foreground light (being that they are fog lights and all) and increased foreground light makes your pupils dilate, which causes them to be less sensitive to light. Meaning you wont be able to see as far.

So my understanding from this is our foglight / highbeam is 1 bulb that just moves up and down aiming the light beam high for high beams or low for fog lights. Correct?

I can agree with the pupils dilating thing but it really isn't that big of a deal. IMHO, how 5000k+ bulbs will tire out your eyes much more since your eyes need to work more to see would be a more important topic to talk about. In most cases, you won't need to see far to utilize your high beams, and in the cases that you are on an open road in the middle of the night, you should be able to see what you need to see just fine even at 100+ mph, and being able to see further isn't going to help since even your high beams can only properly illuminate a limited distance.
I like being able to see what I am about to encounter, thank you.

Pretty much, yes. The H4 bulb has two filaments, and only one can be on at a time. You won't see it used as fog/high too often though. Some cars have bixenon projectors, which is similar only it would never turn off and a shield would move to change the angle the light is aimed, and this light would usually be low/high combo, not fog/high.

I'm sure that last bulb will give the bi-xennon effect.

I don't see how it failed visual with the carb sticker, unless it's missing. Also, I don't know about your smog tech, but when I take my car to the smog station, I pop my hood beforehand and ask them if they can see anything that they might fail visually prior to actually starting the smog test. They're usually nice enough to point stuff out that they're unsure of so you can take care of it before wasting money on a failed visual test.

My MDX doesn't turn off the fogs to turn on the high beams. A lot of cars I have owned or driven never turned off any lights for high beams.

When was the last time the HID bulbs were changed? they lose output over time. If they are still the same bulbs that originally came with the car, you would see a large improvement in output. Especially if you went with a good bulb, like CBIs.
