1) is a template that looks like a magic word but it isn't a magic word. The template inserts placeholder elements that are then replaced using JS with the user's name. JS runs when a user loads the page on their device. In contrast,  is a transclusion of a special page that is interpreted by the wiki while generating the HTML that is sent to the user. Therefore, the tranclusion is interpreted before the JS replace the placeholder with the user's name. As such, when performing the transclusion, the wiki is attempting to find a user who's name matched the placeholder; which there probably isn't any.

2) I don't know the details but I am guessing that this issue is similarly related to the order in which things are interpreted.
