Select N items for wildcards not working as described?

The docs say `{n$$sel1|sel2|...} - Select n items.`, but if you try something like

`{2$$apple|banana|orange}` where you just want it to select 2 out of the 3 options, you get 2-3 options as a result instead of a max of 2:

```
orange apple banana
apple banana
orange banana
apple orange banana
```

is this intended?
