I do things like this sometimes for readability purposes. To shorten the expression may be nice in the final version of code, but while you working on it such short expression makes you (me :) to evaluate it in mind all the time when you read it. Moreover, sometimes you have to break IIF to several sub-IIFs, otherwise you will not be able to keep track of conditions and find the bugs. For example, considering GridHighlighter features, you might imagine the complexity of the final IIF which is stored to Dynamic... properties. You (me :)just cannot work with the expression of that kind in one line.
