UML23 — UML 2: conflicting specifications for how to calculate context for a Behavior

According to 13.3.2 context is calculated as follows: “If the behavior is owned by a BehavioredClassifier, that classifier is the context; otherwise, the context is the first BehavioredClassifier reached by following the chain of owner relationships.” Also according to 13.3.2 ”When a behavior is instantiated as an object, it is its own context.” These two statements are contradictory.

The second quoted sentence is confusing, though the intended meaning is not contradictory with the calculation of the context classifier. The intent is that, when a Behavior without a context classifier is instantiated then, at runtime, the behavior instance acts as its own context object, even though it is not its own context classifier.
