The returned value is used by NotifySubMeshesHypothesisModification() to decide to call subMesh->AlgoStateEngine( MODIF_HYP, hyp ) or not if subMesh is ready to be computed (algo+hyp==OK) but not yet computed.

True result is reasonable for example if EventListeners depend on parameters of hypothesis.
