Recent analysis I've seen also shows an uptick in the importance (and touchiness) of keywords in the image alt text. I'm not sure how this would relate to the idea of "boilerplate" - you wouldn't boilerplate the same alt text into many image tags, would you? But there is definitely an algo factor at work here. It used to be less sensitive than H tags - but at least for now, H tags are tuned way down.
