Difference in scale is a thing between the two.Again, these strike me as differences in scale, not kind. Both have the PC interacting with the world and being told to roll to find out if they succeed. Having to do it in one step or six does not change how it is being adjudicated, just the granularity of that adjudication (and as @Ruin Explorer said, giving the GM plenty of opportunity to GOTCHA).
Both are rolls in an RPG, so they are very similar.
I find this common too.When I ran 5E the players were almost universally confused by the idea of rolling more than once for anything outside of combat.
