Comment(by pracine):

 I think it was the desired behaviour. A choice actually between the upper
 left corner is "inside" the raster of the lower right corner is "inside".
 The should not be both "inside" otherwise both the lower right corner of a
 tile AND the upper left corner of the adjacent corner would both fall into
 two tiles. Remember also that those functions work even if you provide
 coordinates outside the raster. If x is smaller than (or equal to) the x
 upper left then the resulting raster coordinate is smaller than (or equal
 to) 0.
