Ok, I got it now too. Using my example of being at a 350* mark it doesn't matter if the engine rotates the rotor/reluctor 10 more degrees or the mechanical advance does it. It will line up at the same exact phase with the cap and pickup. Boy, why was that so hard to understand.

Now, vacuum advance, that's a different story. Need to look into that next.

So, I was wrong, before. But understand it now.
