I'd say for postdocs it's subtly different, if not necessarily better, than you suggest. With the kind of move we're talking about here, people will often (have to) move out of academia altogether. It's just too rare to find a position that you can transition into smoothly at short notice, and the young academic lifestyle doesn't allow for building up a lot of savings. The burnt bridges to your previous lab won't matter much in industry or government and your experience will typically be valued, but the price is that you are walking away from a career path that might have been your first choice.
