No, if you just increase refcount and is_ref is not set, the values will 
not be referenced to each other (i.e., changing one won't change the other).

It's not supposed to work, you may be lucky, but chances are it'd crash.

If you want the values to be connected to each other (changing one will 
change the other), you need to set is_ref to 1.  Otherwise, you don't.  In 
any case, you must update the refcount.
