Not quite. it’s a telescope. You are gathering more light via the magnifying lenses from the reflection of the dot from the LED. Where the laser is more precise in the amount of light it projects.

0:55, the relative size of the green circle and the white target with and without magnifier is the same so the MOA does not change.
I'm specifically talking about this:
MOA usually measures a bench rest measure of a rifles accuracy. Optics represent a way to improve practical accuracy of a shooter, often under stress to acquire and prosecute a target.

MOA on a dot sight is used to gage the size of the dot relative to the size of the target. IE most Traditional red or Green dots have an illuminated reticle of between 2-4 Moa.
Here is a screen shot from Aimpoint on a product note 2 MOA dot size. This means that if you had a rifle with this dot and fired keeping every round in a 5 round group under the red dot it should have a variance of no larger than 2 MOA.
1 MOA is a group of 1.047 inches at 100 yards.
Holographic sights however typically have more complicated illuminated symbology, and a finer display. Normally with a 1MOA equivalent “Dot” in the center of the display and a larger “Ring”. The center dot is used for precision shooting, however it’s harder to see so the larger ring is there. That ring is potentially as large as 80 Moa. It’s function is to frame the dot making it easier to find. Generally for closer range targets a larger dot. For farther a smaller. In tactical or practical shooting you are probably not going to ever get 1 MOA.

I am well aware of the function of a red dot/Reflex/Hws/LPVO. It’s advantages and potential detractions. It’s not just under stress that these systems have proven fruitful. They allow more rapid sighting and engagement vs the older iron sight system that required alignment of the front and rear apertures of peep, Slider, drum or ghost ring sights. However one has to remember that what you are doing is still an optical illusion based on projection of a image over the real view. Smoke and mirrors, the projection has a size relative to what you are looking at.
