Question about Auditable and Helper in storage model

For "Auditables", an important feature is Jazz Repository will maintain
history states of the item.

But I'm not very sure what will happen if I have a reference to a Helper
in a Auditable. When I get a history state of the Auditable, can I also
get the correct "history" version of the referenced Helper? Or will I
always get latest version of the referenced Helper?

Thanks in advance for any information/ideas on this!
