UMLR — Behavior does not override NamedElement::isDistinguishableFrom() like BehavioralFeature does

BehavioralFeatures and Behaviors use Parameters to specify their signature; however, only BehavioralFeature overrides namespace distinguishability to take into account its signature; Behavior uses the inherited criteria from NamedElement. This means that two Behaviors of the same name and kind but with different Parameter signatures are not distinguishable in the same way that BehavioralFeatures of the same name and kind are.

For example, two StateMachines with the same name but distinct Parameter signatures (in the sense of BehavioralFeature) are not Namespace distinguishable.
It is unclear whether this is an explicit intent of the spec or a bug in the spec.
