Doesn't the last "broader picture" paragraph help explain?

The 2+ methods (of ComboSlot) corresponds to entirely independent events.
The event driven system fires them separately on separate code paths. The
system fires as many of any of these in any order and count.
The only invariant I want to impose is that they are always connected (or
unconnected) in groups. I.e. there is no allowed scenario where a event1
is handled but event2 isn't, and both events are handled by the same
underlying handler (ComboSlot).
Again, is my "broader picture" example useful in anyway?
