How to recognise it
Corner above the slot with white facing right; the edge is beside it in front, already paired with it.
Its inverse is another case
Do the 2 algorithm backwards, F' U' F U, and you are solving 3.
That's why CubeDojo never scrambles 2 that way: it builds a random state with the case fixed, so you practise 2 and not 3.
