Panasonic G7: The A and S modes seem to be the same?

I understood that if I set my camera to the A mode then the camera will auto set the shutter speed and I have not control over the shutter setting.
That does not seem to be the case as I can still adjust the shutter speed using the cameras top front control wheel while in the A mode. It seems the same when I get the camera to the S mode as I still can adjust either the aperture or the shutter speed using the cameras top dials.

Does the S or A mode have a purpose on the camera or can they just be grouped together as a A/S mode?

You seem to be struggling a bit with this camera.

Of course A and S are different modes, you are confusing cause and effect.

In a fixed light environment, when you change one, the other follows.

The way to demonstrate how they work is to fix your ISO, then select A, and watch the S value change when you move from a dark to light scene and vice versa.

The select S, and do the same, you will see A value adjust to maintain the correct exposure.

No I'm not struggling hindesite, I'm just not use to taking photos using other modes as most of the time I use the P mode.

Evidence points to the contrary, did you actually try the demo I suggested? You would have seen that one dial adjusts the setting only, while the other additionally causes the EV display to move from zero.

As the camera had two dials it seemed like one dial was for aperture and the other was for shutter speed

That is correct, when the camera is in use without the dial set switch on.

but I have since learn that both dials do the same thing so when you have the camera set to the Aperture mode then both dials adjust the aperture.

No, that is not correct. Again, you are confusing cause and effect. Look for the highlighted (yellow) aperture or shutter value in the display to see which one you have direct control over. In A ans S mode, the other dial adjusts EV, which of course changes the other values as you see, it is just not doing it directly.

Also, the important thing to note about A and S modes, is that it doesn't matter how you set the aperture, these modes work totally differently for how the camera adjusts exposure.

For example, in A mode with manual lenses, you control the aperture using the lens itself, and the camera can't expose automatically if you are in S mode.

So no, the two modes aren't even close to being the same.
