I would guess the update does. Problem is many ecom sites use the header for adverts to their own products etc. BTW, we have ZERO ads on our sites. I have seen the Google help forum, trouble is there are a fair few on there with the same issues yet the general answer seems to be affiliates have been knocked for 6. They also have never seen the traffic anomalies we have either(traffic spike, conversion drop off, foreign traffic).
