| `31 window2` | `CREATE - window2 at 31s seen 1 times`<br>`WATERMARK - moved to 21` | No grouping at all: we moved out of the first window AND created a new element (if this was `window1` instead of `2`, there would still be no reduce in action here).|

So now the elements in the first window need to be fired and they reach the sink. This is the important part here: the watermark only affects with WINDOWS, not individual elements. |
