Hi Rita,

Terminology is debatable and probably ingrained in current users but I 
prefer "copy" and "clone" as these have similar meanings in other 
software. So: "a copy can be changed without effecting the original 
while changes to a clone effects all it's siblings"... or something similar.

At the moment of creation, it is the same, you will get a copy of the object and all it's scripts. But if you later change an existing script of the original object, the same script of the siblings will change automatically, too. The same script of the duplicates will stay the same as of the moment of the duplication.
