I don't see an easy way to distinguish these cases without modifying the
ejabberd code. The 'unset_presence_hook' is called in both cases,
usually with the same arguments.
Distinguishing these cases sounds like an unusual requirement to me.
You didn't mention *why* you want to deliver offline messages only in
one of these cases. Maybe there's a better way to implement whatever
you're actually trying to achieve ...
