I have not dug into the code but it's pretty clearly that the code is mirroring the image (and adding an offset bug in the other axis) It may be a good feature to add various options for dealing with boundary to the interface since this is clearly a mess on an example like yours. Here continuing the edge colour would be a better choice for example. This is a case where it needs to be chosen according to the nature of the image. There is no "most people want to do ..." solution here. Your case would represent a block graphic image type and the result is clearly unacceptable for the Gimp's "top end application" aspirations.
