you need to add -page +0+0 after each source image

convert neo-000000.png -page +0+0 neo-000001.png -page +0+0
neo-000002.png -page +0+0 neo-000003.png -page +0+0 -background black
-flatten real.png

You seems to have rendered with 3.6 or previous.
My initial reply was assuming (and I tested it) a 3.7RC3.

There is a bright line of white pixel on each left side of partial image.

Just because you can't see it, it doesn't weigh anything,
and you can't drill a hole in it and stick a rivet into it doesn't mean
it's free.
