+Application of Rules
+When there is more than one object category or multiple objects configured
+within a single rule, the following logic is used to determine if the rule
+should be applied:
+* Within one category (WHAT/FROM/TO/WHEN), all objects are logical-or linked,
+  meaning that only one object of any one object group from the same category
+  has to match for the whole category to match.
+* FROM/TO/WHAT/WHEN category match results are logical-and linked, so all
+  categories that have at least one object in them must match for the rule to
+  match.
+When these conditions are met, all configured actions are executed.
 'Action' - objects
