CPYF CRTFILE(*YES) vs CRTDUPOBJ DATA(*YES)

["Graap, Ken" <keg@xxxxxxxxxxxxx>]

When using the CRTDUPOBJ command, the user is required to have more than
*USE authority:

        "The user must have *USE authority (includes object operational
authority, 
              read authority, and execute authority) and object management
authority 
              to the existing object. 

However, there doesn't seem to be the same restriction when executing the
CPYF command specifying CRTFILE(*YES).
My question is ....
If these two commands are functionally the same (they both end up creating a
new file with data in it)...
CRTDUPOBJ OBJ(FILEA) 
        FROMLIB(LIBA) 
        OBJTYPE(*FILE) 
        TOLIB(LIBB) 
        DATA(*YES)

CPYF FROMFILE(LIBA/FILEA) 
        TOFILE(LIBB/FILEA) 
        CRTFILE(*YES)

...why is MORE authority required when using the CRTDUPOBJ command?
