Should Hiring Manager on a req ignore the Position Hierarchy until the pending worker converts?

We are seeing that the Hiring Manager selected on a requisition becomes the Line Manager when the pending worker record is created for a hire into that requisition, irrespective of the incumbents in the Position Hierarchy. If we manually edit the pending worker record, then the Line Manager will update accordingly, but only upon manually editing the pending worker.

While I found the following knowledge article where Oracle confirmed that Position Sync does not include pending worker records, I also found Oracle documentation for ORC that suggests the Hiring Manager field is pulled from the incumbent of the Parent Position of the position used in the job offer.
