This is because Current is not a renaming of Current_Hook, which is what 
gets the new value. In the common case, in which the renamed object gets 
a new value, then the renaming also reflects the change. In the example 
above, if the assignment were to Current_Hook.all, then Current would 
also change. See ARM 8.5.1.
