Now lets put the distributer at 350 degrees, or 10 degrees before the next alignment. Add 10 degrees for the mechanical advance rotation of the rotor and reluctor and we have another perfect alignment for a energize. Sure the reluctor and pickup are now energizing at the same exact alignment , but guess what. The rotor is now 10 degrees rotational different from the cap.

The rotor is indeed 10 degrees advanced from where it was before compared to the cap , but yet the relctor/pickup alignment is the same.

I can see why this is hard to get the head around.

This is where you go wrong. If the reluctor is 10 degrees before the alignment, and the shaft is spinning fast enough to already have the advance working, that means in 10 more (shaft already advanced) degrees it will fire in the same spot as it does without the shaft advanced. The advance happens before the reluctor. The rotor will end up at the same spot as the trigger point every time.
