--- Comment #12 from Rafael Weinstein <rafaelw@chromium.org> ---
The idea is that any given transient registration is associated a given
"source" observer registration. In the case we are discussing, when the options
of that registration are removed, then the transient registrations associated
with it must be removed.

It's similar to the step upon delivery: "Remove all transient registered
observers whose observer is mo.", but that removes all transient registrations
associated with observer. In this case we need to remove only those associated
with a given registration *of that observer*.
