In the output the pixel sizes are positive Pixel Size = (10.000000000000000,10.000000000000000).
However, this creates some problems with various gdal tools, e.g., creatinge VRTs or Mosaics:

Additional context
This is not really a but since it is not wrong per se, but the input/output should be consistent in my opinion.
