The difference is that with 3 roll 2, you really can't tell there's a top button even when it's not buttoned because it rolls completely over (except for maybe the hole). With 3 roll 2.5, it rolls over the top button, but you can often still see it. At least that's my interpretation. I usually just call them 3 roll 2 regardless.
