It's not that it's "more sophisticated" - quite the opposite, in fact. The reason there's the limit is that ePub supports CSS, and hence has to maintain state information for every part of the text. When the ePub reader opens a file, it has to parse it, and hold that parse tree in memory. The Mobipocket format, which the Kindle uses, is stateless. Only the page currently being displayed is loaded into memory, and there's no parse tree, hence much lower memory requirements. (The new Kindle "KF8" format, however, basically is ePub, and works the same way that ePub does.)
