There is a difference between the bullwhip effect and JIT (just in time) manufacturing. Building your assembly plant near your suppliers is JIT and it helps reduce in-process inventory. Less in-process work and faster delivery to the assembly plant means you can ship product faster. This is important for a fast-moving tech manufacturer.
The bullwhip effect is caused by delay and uncertainty in demand. JIT helps minimize its effects, but doesn't ensure its elimination. Coordinating your demand with retailers is one way to prevent the bullwhip effect. I'm guessing Apple has effective inventory and order coordination with their retailers.
