That should be
  right x*(Max-Min).x
  up y*(Max-Min).y

It took me quite some looking and head scratching to spot that one. :-)

'up' and 'right' are vectors and you're using a float (i.e. just the x 
dimension of the difference between the Max and Min extents of the object). 
This gets automatically expanded to a vector with equal values for x, y, and 
z, so you need to multiply by the appropriate vector (e.g. 'x') to get a 3D 
vector with just the 'x' component being '1' and the rest being '0'.
