[pointerevents] Relationship between main pointer event and coalesced events (#409)

jakearchibald has just created a new issue for https://github.com/w3c/pointerevents:

== Relationship between main pointer event and coalesced events ==
It isn't clear to me how the [coalesced event list](https://w3c.github.io/pointerevents/#dfn-coalesced-events-list) works.

If I have a trusted event from `pointermove`, should `event.getCoalescedEvents()` ever return an empty array? It does on Firefox Android.

Let's say `event.getCoalescedEvents()` returns an array of two items:

```js
const [one, two] = event.getCoalescedEvents();
```

What's the relationship between the single points expressed by `event`, `one` and `two`? Is `one` or `two` representing the same point as `event`? If not, where does the `event` point appear in the sequence?
