for example the code:

Yes.
Maybe.
If initSpecial calls [super init], some supers discard the original
object and return a new one.
I think you're confusing this with a different init pitfall. The
above two methods are in fact identical. In the first, *whatever* -
initSpecial returns (even if it's not the original receiver) will be
assigned to the local variable self, and that value will be
returned. In the second, *whatever* -initSpecial returns will be
returned immediately.
You might be thinking of the mistake some people make when they
separate the call to +alloc from the call to -init.
