The space you'll have between the NDS crank arm and the cup looks perfectly normal to me but you haven't shown what it looks like with the crank arm on so that's only a hunch. In my experience after the crank arm is pressed on there's typically only 2-3mm between the cup and arm. Obviously a lot more space is required on the drive side but unless if you have super flared chain stays it shouldn't be an issue on the NDS.
I was only addressing the concept of a potential complication if this was a 70mm shell, and even then - just potential, because the angle of the seat stay emerging from shell would change as well. But my original question related to whether I was simply using this spindle with cups that were too thick. Thinner cups would give better extension beyond the face, and the thought came up because I'm used to seeing the following spacing on the NDS side...
a bit more space from the face to the beginning of the taper. But yes, I have seen less as well...
