help me to get the idea of this work..

Hi all,
I try to understand the scripts of path tags animation:

http://old.hitmo-studio.com/services.html

,but when I try to change the position of the rectangles and paths,I don't understand the idea  
of setting the initial values for  "d" property for the "path" tag,which u will see in "svgObjectsData" array
in scripts.js to get the final value.
I can only set an immediate value for the d property ,but this doesn't work with the animation.
Can someone check that and help me ..plz 
Thanks.
