Are you sure the layers have not moved? I usually add this expression to layers that I am going to rotoscope. 

[width,  height] / 2

This will keep layers centered in the middle of the comp.

Hello sir. I am sorry i didn't get completely what you are trying to say, actually i am new to this software, so can you tell me how to use this particular expression while rotoscoping by giving an example stepwise?
