Edited comments for NESTABLE_ASYNC events

The documentation for NESTABLE_ASYNC events is not quite right. It does not say
that we use "id" to match events, and it is not accurate about the parsing rule
for unmatched events. This CL makes changes to the comments, so it will be
clearer to future users of the API.
