Or does it REALLY matter, since they will be turning anyway... I've tried different ways, and haven't noticed any real difference.

That thing confused the heck out of me.
I generally set the top and second rings 180* apart, and the oil rings between the wrist pin hole on the non thrust side. I don't know if it really matters since they all spin round and round. But at least that's where they start. When in a hurry I have just put them on "where ever" and haven't noticed any difference.

I've always put them at 180* stagger, with the expander at, say 9 o'clock, the bottom rail at 2, top rail at 8. Bottom compression ring at 10, top ring at 4 forming an 'X' pattern. It seems to work for me... I leaked down my motor and came up with 2-3%

Yea, that is confusing...

From the look of the valve notches, the piston on the left would be rotated 90 degrees clockwise, and the one on the right 90 degrees counterclockwise.

This would put the top ring AND oil expander pointing towards the front of the engine. The second ring would point towards the rear, and the oil expanders would be staggered towards the rear.

I think....

The thing I do not like about the method shown is all the oil ring gaps in the same quadrant of the piston.
I would put the 2nd ring gap where they show the 1st ring gap. 2nd ring is primarily oil control.
I'm sure the suthor could give reasoning at extensive length but the rings do move around so any arrangement can become meaningless beyond satisfying yourself at assembly time.
