Take a look at this: http://tiddlywiki.com/static/ListWidget
The variable property sets the name of the variable that the list widget will store it's value in. By default it sets the variable "currentTiddler" overriding the current value of "currentTiddler". In mario's code, it sets a variable named "ignore", so if inside the loop you added "<<ignore>>" you'd see the current value of the list widget. But since you don't use that variable, it's just a convenient way to avoid overriding the "currentTiddler" variable.
