Are the subscribers of this newsgroup supposed to believe that “Doc O’Leary” 
is your real name?

“this” is not necessarily referring to the same object that the function is 
called as a method of.

The original code of the function is:

  function ObjLayerMoveTo(x, y) {
     /* 100+ lines of spaghetti code */
  }

"foo" is a primitive string value there.
