you must set the (assoc 11) group to be at the point where the alignment is..this is why you see them as "slightly different". If you want the text to remain in the same place but have a different justification then you will need to calculate where that alignment point is and set the (11 . XXX.X XX.X XXX.X) to the appropriate value.
Hint, use (textbox) (assoc 50) and (polar) to determine that point.
