A gdalinfo on the resulting file does not report any geotransform and then use the default (0,1,0,0,0,1), which is almost the good one except that pixelYSize should be -1. A listgeo reports: ""Corner Coordinates: ... unable to transform points between pixel/line and PCS space"" If I try with another origin (1, 1) or pixel size (0.5, 0.5) it works...
