The why is quite simple to understand: the faster a page is able to fully render, the quicker all components can drive down to their idle power states."
AnandTech's 3G benchmark scores for the iPhone 5 and Nexus 4 are 4.55 and 4.15, respectively. It's only when the iPhone 5 runs on 4G LTE that it scores 8.19.
And while I appreciate AnandTech's quantitative reports, I'm not sure you can call this "typical usage", unless you typically spend all day refreshing web pages.
