No, this is not the case -- Ken's reply was correct. If you use
automatic KVO notifications, your accessors will still have side
effects.
Although I should add that of course by the time you reach dealloc you
should not have observers...
The general point still stands, though. The correct pattern is:
Set instance variables directly in init methods, and release them
directly in dealloc.

Other than in init, you should always use accessors to set values
because:
(a) The accessors might have side-effects (such as emitting KVO change
notifications) that your application relies on;
(b) Accessors are typically the best place to put memory management
code. If you push "all" your memory management to accessors, then
you're much less likely to make a mistake somewhere along the line...
