I think I know what is going on...
the Append like -flatten -mosiac -border etc etc etc all create a new
canvas onto which to compose the images given.
The problem is the canvas has to be created with some color.
For -append that canvas is created with the -background color
so that is what you is the areas that were not 'Copy' overlaid by
the append operation.
Try
convert image_one.png image_two.png \
-background none +append output.png
See IM examples, Layers of Multiple Images, Append
http://imagemagick.org/Usage/layers/#append
The first example did not have any problem as all the images are all the
same height.
Later examples show how -background is used by append. and how you can
fudge a center aligned append, until some type of justification setting
is added to IM.
