Significance of Allowing to Create PO and Supplier Contract From Same RFQ

Content

Dear Team - Need clarification on the below scenario.

--> I have created an RFQ, the supplier has responded to the line prices, closed the RFQ, and after the Award process is  "completed", I am able to create a "supplier contract" and add the RFQ lines to the supplier contract.

--> After creating a supplier contract i am again able to create PO document from it and the PO document does not hold any reference to the Supplier contract.

So the question is what is the significance/use case of creating two output "PO" and "Supplier Contract" from the same RFQ ?
