Having worked in 30 or so countries myself I'd say there's a huge difference between being there for a few months and living there for a couple of years.
I'm not saying that it somehow "doesn't count" but it's not the same thing. I've certainly enjoyed being in a new country for a few weeks or months, as long as that time wasn't simply spent going from the hotel to work each day.
However, spending a year or more there and living more like a local is a vastly different experience and reveals a lot more about the country and the people.
On the other hand I've seen some, mostly Americans for some reason, who get moved by their firm and live in a kind of bubble only really interacting with other expats with the firm organising everything for them. I find it hard to see that you'd gain a lot from living abroad in those kind of circumstances.
