[pointerevents] Unclear note about PointerEvent initialization of attributes to reflect coalesced events (#374)

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

== Unclear note about PointerEvent initialization of attributes to reflect coalesced events ==
As part of the section relating mainly to coalesced events, the spec contains the following note:

> NOTE
> The PointerEvent's attributes will be initalized in a way that best represents all events in the coalesced event list. For example its `movementX` and `movementY` ([POINTERLOCK]) COULD be the sum of those of all the coalesced events.

I'm actually unclear on what this note is trying to say. Right from the start, "The PointerEvent's attributes" ... which pointer event is it referring to? The coalesced "parent" pointer event that has the list of non-coalesced pointer events? If so, is this trying to define (in a non-normative note, but still) what a user agent could do? The spec already says that it isn't trying to define this. Wonder if the whole note should not simply be removed?

If it's to be kept, it needs some disambiguation perhaps
