The point is that they're cutting 10% from planned production, rather than previous quarter production. This implies less than projected demand, which means they may miss their sales forecasts.
Considering Apple just released a letter to stockholders noting that their projections were too high and directly pointing to poor iPhone sales as the reason I'm not sure what your comment is trying to say.
My comment is trying to say that this is still likely just another of the essentialy fake supply chain doom stories that happens to coincide with a genuine reduction in sales in the weakening Chinese economy.
