All I can do is to repeat Joe's words literally
"Atomic increment and decrement instructions are not by themselves
sufficient to make reference counting safe."

Replace "by themselves" with "alone", and "reference counting"
with "reference counting in the presence of shared structure
members", and you find that your statement and Joe's are equivalent.
*Of course* reference counting is about shared structure members.
That's it's primary purpose.

Martin
