I had a look at the code and the results on GNUstep, concluded that everything was probably working properly, and ran it (slightly adapted version) on MacOS-X to make sure.

The reason you only see one image in the flipped view is that it is drawn with its origin at 0.0 which is the top-left corner of the view.
The composite operation puts the bottom left corner of the image at the specified point ... so the bottom left corner of the image is at the top left corner of the view and the image is therefore drawn outside the view and entirely hidden by the view's clipping.

The reason the other image appears at the same position in both views is that it is drawn at 64,64 which happens to be half way up the 128*128 view whether the view is flipped or not.

attached source contains 2 views, which each composite 2 images
one is flipped one is not, the flipped view only shows 1 image.
