What I wrote was information from one of the engineers on the LR team. Working in LR is most definitely NOT the same as working in Photoshop. Lightroom is a parametric editor, Photoshop is a pixel editor. Entirely different operations.
But I suggest you experiment and see what happens for yourself. After all, anything you do is non-destructive and you can go back to the beginning without a moment's thought.
