This would be the "simplify FLWOR expression:" returned just above the "Optimized Query" section of the info window?
I suggest to take another look at the items in the drop-down list of the info view.
Do you find the item “Query” still relevant for further displays?
Sure!
The teaching use is to compare the Query, the Optimized Query, and the steps in Compiling.
One of the core things with any declarative language is to not argue with the optimizer, and looking at those Info items for simple things, particularly XPath, helps build a sense of what the optimizer expects.
If the Query return has been rendered on a single line, well, XML doesn't consider white space significant, and a few reminders of that do no harm.
