Thank you for pointing that out. It seems that "oops I did it again".
What are the rules for the order of the invocation of triggers defined for some table?
If several triggers are defined which one if executed first?

No, it's not the same. Consider the implications of the constraint
you added:
ALTER TABLE reseller ADD CONSTRAINT FK_reseller_parent
FOREIGN KEY (parent_id) REFERENCES reseller(reseller_id)
ON DELETE CASCADE ON UPDATE CASCADE;
^^^^^^^^^^^^^^^^^
This will cause the delete of reseller_id 1338 to propagate to the rows
in which 1338 appears as parent_id. Which sure looks to me like it's
the behavior you're complaining of.
