thats because of the coordinate-system:

the origin is not in the lower left with y-values upward, but in the 
upper left with y-values downwards:
(0,0)----(100,0)----(200,0)
  :        :         :
  :        :         :
(0,100)--(100,100)--(200,100)
  :        :         :
  :        :         :
(0,200)--(100,200)--(200,200)

Text is originated in its lower left:
    .------------.
    |Text example|
 -> +------------.
    ^
therefore your values are are neccessary.
