Being that I have worked in numerous machine shops I can tell you what you did doesn't make any mechanical sense...just sayin.

I didn't remove any metal and an orbital sander doesn't really spin at high speed. It just basically removed all the pad deposits and all the glaze off the face of the pads. Obviously removing actual metal this way would result in an uneven surface, which only turning would restore. I finished the rotors with scotchbrite too.
If it doesn't last then I'll look into new rotors and pads but no cost except for time means I had nothing to lose.
I put in a full day of spirited driving today and so far so good.
