It does allow you to play both periods yes. And you can fix it with the stats proposed - although some differences will remain. There are also some improved stats proposed for the Mongol Invasion campaign - the mongols are too strong. I think there is a thread in the Sword Dojo about it, and the person who knows most about it seems to be Orda Khan.
PS The remaining differences are the cost of buildings and the fact that the AI does not get money to build infrastructure when bankrupt and finally the inclusion of the manual pillage. In the original buildings cost quite a lot, and the economic aspect is far more challenging - unfortunately this can't be changed in the WE. Also the AI in the original will keep building infrastructure regardless of whether he has money (or hasn't). Last but not least the player can't manually pillage or disband in the original - these are not options - while in WE they are just like in MTW. I personally find that these make a significant impact in the game.
