You're assuming that your static assets (js, css, images) aren't served from a CDN (pretty much the standard at companies like Yahoo!). When your main server is serving just the HTML it's much more likely that your requests could double.
Any website serving its assets from a CDN will be a) unlikely to make a mistake like this empty image src thing, and b) have a well-cached front-page that would be unlikely to impact on server load.
Maybe. It's still a bit alarmist though. For 99% of sites, it will barely have an effect. Best practices for websites serving millions of pages a day truly are different than for websites serving thousands of pages a day. They are also different for web apps versus largely static pages. There is too much emphasis on absolutes in the web development community.
