Note vs Comment behavior when anchored to Diagram

When anchoring a Note to a diagram and then selecting “Text display mode” > “Show Documentation” the Note displays the Diagram’s Owner’s Documentation.
When anchoring a Comment to the same diagram and then selecting “Retrieve Documentation” the Comment displays the Diagram’s Documentation.
Is this the expected behavior for Note and Comment?
If so, what is the rationale for the difference?
